The triple points of sulfur hexafluoride (TPSF6), carbon dioxide (TPCO2) and xenon (TPXe) have possibility as candidates for replacing the triple point of mercury in the International Temperature Scale of 1990 (ITS-90). Herein, we report the development of an apparatus for realizing the TPXe and two cells using Xe samples from two difference manufactures. The temperature of the TPXe was evaluated as 161.406 13 K ± 0.33 mK. We also investigated replacement of Hg with one of the three (Xe, CO2 and SF6) in the ITS-90 subranges involving the Hg fixed point. The differences between the ITS-90 temperatures and those temperatures obtained using each alternative scale were found to be within the uncertainty of the ITS-90 values. Variations between values for the different temperature subranges were also within this uncertainty. These results suggest that alternative standard materials such as Xe, CO2 and SF6 could replace Hg in the ITS-90 without changing the form of the interpolation functions. [ABSTRACT FROM AUTHOR]

In this study, thermal creep flow around a set of plates, periodically set in a pipe, was simulated using the direct simulation Monte Carlo method with a variable soft sphere molecular model for elastic molecular collisions and a statistical inelastic cross section model for rotationally inelastic molecular collisions. The surface temperature on one side of each plate was set higher than that on the other. The computational flow field was modeled using a drive source consisting of Peltier devices in the experimental pump system. The simulation results suggested that the pressure increases from low-temperature to high-temperature surfaces in a stepwise manner and that the simulation model acts as a pump by generating thermal creep flow around each plate.

Fiber-reinforced thermoplastics (FRTPs) have been used for wide variety of applications due to their high mechanical performance and light weight. The properties of molded FRTPs depend on the fiber length and they increase until the finer length in them reaches a certain length. However, it is difficult to keep the length long in the compounding and molding process avoiding the fiber breakage. Based on the above background, the objective of this study was to predict the degree of fiber breakage and control the fiber length in compounding process using the twin screw extruders. Two different laboratory sizes of extruders were used to observe the carbon fiber length in polypropylene matrix. The screw configurations composed of full-flight screws only and the combinations of right, left, and neutral kneading blocks. In the former case, the fiber breakage was caused by the full-flight screw only, suggesting the screw root depth had a significant effect. In the latter, it was cleared that fiber breakage rate was correlated with the mean shear stress obtained by the 3D numerical simulations. [ABSTRACT FROM AUTHOR]

Injection overmolding process is promising process for fabrication of thermoplastic composites which has excellent mechanical properties and complex shapes. Concretely, the continuous fiber-reinforced thermoplastic composites are fabricated by stamping process as substrate. Followed by the melt polymer is overmolded onto the substrate by injection molding for fabrication the ribs and bosses. Therefore, in this process, joining strength between two materials is a major factor in the mechanical strength of a product. As the new approach to improve the joining strength, nanofiber-filled thermoplastic film is inserted between the substrate and overmolded polymer for reinforcing the interface directly in nanoscale. In our previous works, we revealed that multi-walled carbon nanotubes (MWCNTs) filled polypropylene (PP) films could improve the interlaminar shear strength. However, it is still unclear cause why interlaminar shear strength increased by adding the films. In this study, to clarify the influence of nanofiller size on the adhesion strength, two kinds of nanofillers, CNTs and vapor grown carbon fibers (VGCFs) were used. As a quantitative evaluation method of adhesive strength, a tensile overlay shear strength test was performed. As a result, it improved the joining strength at CNT contents of 0.5wt% of CNTs film the best. CT scan images confirmed that CNT tangled with polymer chains. This indicated that entanglement between CNTs and injection resin has effect on the adhesion. By diffraction scanning calorimetry (DSC) data, the crystallinity of nanofiller-filled thermoplastic film was lower than PP film and it was considered that addition of nanofiller distracted crystallization PP. Therefore, although the crystallinity of substrate surface decreased by adding nanofibers, CNT contents of 0.5wt% was the best contents for joining strength. Consequently, the relationship between crystallinity and joining strength requires detailed investigation, such as focusing on crystallization behavior during cooling. [ABSTRACT FROM AUTHOR]

Electrical energy in Indonesia comes from various power plants. One of the energy sources used is solar energy with a usage percentage of 0.003%. The potential for the use of solar energy is still very large, especially in Indonesia with tropical regions. Solar energy can also be used in making learning media in the form of trainers. Based on trainer observations conducted at the Energy Conversion Laboratory of the Department of Electrical Engineering Universitas Negeri Malang, Indonesia, there are solar power generator trainers that not suitable to support the Energy Management Course because there are no energy production control and load management features. While The energy management course discusses control of energy production and load management, so it is necessary to develop trainer to achieve the learning objectives of energy management courses. The development model used in this research is based on Sugiyono's model. The validation process was done by expert 1 and expert 2 while the product also was tested on undergraduate student in the Electrical Engineering and vocational student of Electrical Engineering who have already studied about Energy Management Courses. The validation result of trainers shows the average percentage of 94.2% while the job sheets as the support material for trainer has validated with the average percentage of 94.3%. This result shows the eligibility category is very feasible. Furthermore, the testing result of trainer which is done by students has the average percentage of 93.1% while that of the job sheet has the average percentage of 92.8%. This result means that the eligibility category in the testing case is also very feasible. From the results of the data analysis, it can be concluded that the IoT-based energy monitoring system trainer and the energy management job sheet is feasible to use in the learning process of the Energy Management Course, Department of Electrical Engineering, Universitas Negeri Malang, Indonesia.

COVID 19 pandemic has affected all aspects of life including Nonformal Education field. This outbreak gives impacts on the change of services and learning patterns in nonformal education unit, almost in all parts of the world. Indonesia and Japan are no exceptions. The differences in condition and culture in these countries are unique and interesting to study and compare with in relation to the pattern of change occurred during the COVID 19. The aim of this study is to find out learning condition in nonformal education unit in Indonesia and Japan during COVID 19 pandemic period. The study used mixed method of Sequential Explanatory Design, by collecting them through document and questionnaire in Community Learning Center (PKBM) and Japanese Community Learning Center (Kominkan) in Japan. The data were collected for three months, involving each researcher in each country. The results showed that condition of nonformal education service in Indonesia and Japan changed from the offline model to the online one, long distance learning through zoom, social media, and other applications supporting education services for society. Innovation in nonformal education services in Indonesia is in the form of online services through LMS, Video Conference, Social Media and other media, whereas, in Japan, the innovation service has created two types of Kominkan, "formal", learning through Zoom, bulletin and social media, and "informal", learning by referring to discussion activities and communication building. Some challenging factors experienced by these two countries with regard to the services are the management program in the future and the use of technology in the learning process. In Indonesia, the limitation of Educators and Education staffs and learners has become one obstacle, while in Japan, apart from most learners are elderly, making it difficult to handle, the internet safety becomes another issue. Factor supporting the service in Indonesia is that PKBM has a quick response to the change of learning pattern and COVID 19 pandemic, although it still needs service management betterment. Meanwhile, in Japan, the supporting factor includes social education services that can give different kinds of activities by making use of various platforms. [ABSTRACT FROM AUTHOR]

We consider the possibility of having hybrid stars with a phase transition from hadrons into strange matter at the core of a neutron star in β equilibrium. For the hadron phase equation of state (EoS) the quark-meson coupling model is used, while the MIT bag model is used to describe the strange matter phase. The phase transition is treated using the Gibbs construction method and results are calculated and checked against the observational constaints imposed on the EoS. The results are also compared with the hadronic EoS including hyperons, F-QMC700. [ABSTRACT FROM AUTHOR]

The beta-detected nuclear magnetic resonance (β -NMR) technique is a novel method that obtains depth-resolved information on samples by observing the asymmetric beta decay of nuclear probes. Although the beta-detected NMR has several advantages over the conventional NMR techniques, the number of user facilities in the world is severely limited. At the site of Korea Multi-purpose Accelerator Complex (KOMAC), we initiated a research project to develop a radioactive ion (RI) beam facility dedicated for the future beta-detected NMR facility at KOMAC based on a 100-MeV proton linear accelerator. In this endeavour, we developed a prototype of a target-ion-source (TIS) composed of low-Z production targets, target container, target heater, high-current feed through, and hot surface ion source. In recent on-line experiments, we have demonstrated that a Li-8 beam of the order of 106 pps could be extracted with the prototype design of the TIS. Here, we present the recent progress of the RI beam development study. [ABSTRACT FROM AUTHOR]

Systematic and anomalous trends in fragment mass and TKE (total kinetic energy) distributions are investigated in terms of the 4D Langevin model developed at Tokyo Tech. We have found that correlated transitions in symmetric components and dominant modes (symmetric v.s. asymmetric) can explain the prominent systematic and anomalous features of fission observables. We have also elucidated that interplay between spherical and deformed magicity at A=132 and A=142 to 144 is important in both observables. [ABSTRACT FROM AUTHOR]

Research on nuclear forces between the nucleon and the hyperon has been studied mainly on experiments on measuring the binding energy of hypernuclei. We thought that we understood the hyperon-nucleon force because theoretical models based on experimental data could reproduce many hypernuclear data. However, for recent H Λ 4 (pnnΛ) and He Λ 4 (ppnΛ) data, the theoretical Λ Λ model does not reproduce the binding energies of the ground and excited states. In these two hypernuclei, only p and n are replaced by one, and the expected binding energy is simply expected to be dominant due to the effect of Coulomb force. Experimental data show differences that cannot be explained by the theoretical model and the problem called charge symmetry breaking (CSB) in ΛN interaction. The key to solving the problem is to measure Λn forces that have not been measured with good accuracy. To measure the force between Λ and n, which cannot perform direct scattering experiments, we are preparing an experiment to measure the K+ production cross-section modified by the Λn final state interaction in the γd→K+Λn reaction. The experiment will be performed with a real photon beamline generated from a 1.3 GeV electron synchrotron in Research Center for Electron Photon Science (ELPH), Tohoku University. In the beamline, we have been conducting K0Λ production experiments using the NKS2 spectrometer. We are developing a new detector to measure K+, and report on it. [ABSTRACT FROM AUTHOR]

Globally, there has been a general increase of women in physics. However, they are still under-represented as compared to the other sciences. As to date, only three women have been awarded the Nobel Prize in Physics out of 51 female Nobel Laureates since 1901. The percentage of women laureates has roughly doubled in the 21st century. In Malaysia, national policies that aimed to have women holding at least 30% of decision-making roles by 2020 were put into place since 2011. This has been quite successful in increasing gender diversity in Malaysia. Furthermore, Malaysia's education system is different because of the secondary education system style of rote learning that could be better suited for females and the system is gender blind. Taking a case study of entrants in a Bachelor's degree programme in Physics in Universiti Malaya, the average gender parity index (GPI) over the past 5 years is 0.89. This is lower than the national GPI of 1.27-1.37 for Bachelor's degree entrants in Science, Technology, Engineering and Mathematics (STEM) in public universities. At the PhD level in STEM, the GPI drops to 0.77-0.95. The average GPI for faculty members in Department/School/Programme of Physics of 11 Malaysian universities is 0.80. [ABSTRACT FROM AUTHOR]

The KAGRA collaboration is a scientific organization for the gravitational-wave (GW) detections and GW astrophysics. It consists of more than 360 members from 14 different countries as of June 2019. Regardless the host institutions are the university of Tokyo, National Astronomical Observatory of Japan and KEK which are all in Japan, and regardless the experimental site is in Japan, there are many international members. However, in the collaboration, women and non-Japanese collaborators are still minorities. To accelerate the scientific efficiency, making a comfortable work environment for any members is a key. As a first step, we conducted an online demographic survey. In this article, the result of the survey and our efforts to make better collaboration will be shown. [ABSTRACT FROM AUTHOR]

The first synchrotron light source in Thailand was established in 1996, Siam Photon Source is operated and developed the capability of the facility to increase the energy up to 1.2 GeV by Synchrotron Light Research Institute (SLRI). Many users from both inside and outside the country come to use the synchrotron light which is increasing steadily. As a result, Siam Photon Source II at 3 GeV project is taken place in 2019. The Hard X-ray absorption spectroscopy has been planned to support which two consideration designs of the X-ray energy range are 2.4 – 40 keV at the first and 4 – 35 keV at the second. The scattering synchrotron radiation can occur from the optical components in the beamline. The radiation must be controlled to be safe for the utilization of synchrotron radiation in which the radiation shielding design is taken into account. This work aimed to compare the first and second HXAS beamline shielding designs to evaluate the dose distribution to prevent the radiation scattering. The dose calculation was performed by STAC 8 program, therefore, estimate the radiation dose level at the surface outside of the beamline both optic hutch and experimental hutch. The results of the two design indicated that dose distributions with the scattering angle were below the design criteria at 0.1 µSv/h. The optic hutch shielding wall for the first design is below the second design while the experimental hutch shielding wall for the first design is higher than the second design.

We study a ferromagnetic instability in a single-band Hubbard model on the hypercubic lattice away from half filling. Using dynamical mean-field theory with the continuous-time quantum Monte Carlo simulations based on the segment algorithm, we calculate the magnetic susceptibility in the weak and strong coupling regions systematically. We then find how ferromagnetic fluctuations are enhanced when the interaction strength and density of holes are varied. The efficiency of the double flip updates in the Monte Carlo simulations is also addressed. [ABSTRACT FROM AUTHOR]

Within the framework of Categorical Quantum Mechanics, it was found that orthogonal bases are subsumed by the so called classical structures. So, there must be classical structures which have the eigenbases of the Pauli X,Y and Z operators as their underlying bases. In this article, we propose a procedure for composing these classical structures on a single qubit which produces classical structures on multiple qubits. As a result, we can present orthogonal bases within a multiple qubit system as diagrams which makes explicit the entanglement structure of those bases. [ABSTRACT FROM AUTHOR]

The Peer Instruction approach developed by Eric Mazur is often applied to a physics class. Reflection and discussion in this method is effective for students to engage deeply with the content during classes. However, some students may be silent during discussion time. In order to investigate a relationship between participation to discussion and learning outcomes, the volume of speaking voice for each student in Peer Instruction was measured in this study. Our study was used to investigate the introductory physics course at Hokkaido Information University. As a result, it was found that approximately 64% of participants in the class talked in discussion and the percentage of correct answers after discussion increased for those students, while the students in silence did not increase so much. This result supports quantitatively the effectiveness of Peer Instruction. However, the existence of silent students raise the problem of why they do not talk. Furthermore, it proposes a question of whether making such students talk is necessary or not. [ABSTRACT FROM AUTHOR]

In this paper we discuss the misconceptions detectable in Force Concept Inventory responses by analysing student selection of distractor items. We discuss the appearance of distinct, coherent, clusters of distractor items which appear in this data. Certain distractor items are structurally central in these groupings and sub-groups within these clusters may be interlinked by "connector" items. Our analysis suggests that these clusters represents a coherent, robust, non-Newtonian worldview. We further suggest that this worldview could be destabilised by correcting a small number of conceptual mistakes. [ABSTRACT FROM AUTHOR]

In this work, we study the one plus half-monopole configuration in Weinberg-Salam model, covering ¢-winding number n=1. We observed that while the finite separation between the one-monopole and the half-monopole becomes larger as compared to the same configuration in Georgi-Glashow model, a flux tube is established, creating a bound-state of one-monopole and half-monopole in Weinberg-Salam model. There is no electromagnetic current loop circulating the pair of one-monopole and half-monopole, but the system possesses non-vanishing magnetic dipole moment. The non-Abelian gauge potential and the electromagnetic gauge potential are singular along the negative z-axis, but the total energy is finite. The solutions are investigated by fixing the Weinberg angle while varying the Higgs self-coupling constant and vice versa. It is shown that this configuration in Weinberg-Salam model possesses different behaviours than its counterpart in Georgi-Glashow model. [ABSTRACT FROM AUTHOR]

In this study, we investigate the Monopole-Antimonopole Pair (MAP) solution in the SU(2)×U(1) Weinberg- Salam theory with ¢-winding number, n = 3 for bifurcation phenomena. At n = 3, the 't Hooft-Polyakov monopole merges with antimonopole to form a vortex ring. Other than fundamental solution, two new bifurcating full vortex ring solution branches were found when Higgs coupling constant, λ reaches a critical value λc. The two new branches possess higher energies than the fundamental solutions. These solutions behave differently from the vortex ring configuration we studied in SU(2) Georgi-Glashow theory. We investigated on the total energy E, vortex ring diameter dρ, and magnetic dipole moment µm, for 0 ≤ λ ≤49. [ABSTRACT FROM AUTHOR]

We have investigated theoretically the missing-mass spectral function of (π−, K+) reaction on 9Be target to populate ∑−pLi ∑-hypernucleus. If there is an appreciable amount of ∑N-ΛN coupling effect, this double charge exchange reaction would be a plausible way to populate neutron-rich Λ-hypernuclei. We have used Plane Wave Impulse Approximation Method together with ∑-nucleus Woods-Saxon potential. It is found that the strengths of V∑=−20 MeV and W∑=-3MeV give an observable narrow peak in the spectrum of ∑−9Li. To investigate the Λ-L coupling effect and ∑ mixing component Λ9He, we also studied the structure calculation of Λ9He by solving the coupled channel Schrodinger equation. Λ-∑ coherent coupling effect is 0.19 MeV and ∑ mixing probability is 0.2% in Λ9He. [ABSTRACT FROM AUTHOR]

It is known that universe began with a hot big bang with radiation dominated era involving photons. For this reason, photons are studied at finite temperature. In order to determine thermal effects on photons, calculations of longitudinal photon self-energy are made within real time formalism in mixed space. [ABSTRACT FROM AUTHOR]

The primary target of ILC 250 is to precisely measure the coupling constants between the Higgs boson and other Standard Model particles. For this, we need to precisely calibrate the energy scales for various particles. In this paper, the necessary calibration methods using the e+e− → γZ process will be discussed. We will focus on the photon energy reconstruction methods and report the calibration precision. [ABSTRACT FROM AUTHOR]

In this talk with chiralities, I present a solution of the long standing gauge hierarchy problem with a hidden sector SU(5)' with representations 10 ¯ ⊕ 5 ¯ ⊕ 2 ⋅ 5. Sideway remarks are on NATURAL HILLTOP inflation and a bound on the QCD angle θ ¯ . [ABSTRACT FROM AUTHOR]

We investigate the gauge/gravity duality between the Ν = 6 mass-deformed ABJ theory with Uk(N+l)×U−k(N) gauge symmetry and 11-dimensional supergravity on LLM geometries with S O (2 , 1) × S O (4) / ℤ k × S O (4) / ℤ k isometry and the discrete torsion l. We obtain the vacuum expectation values (vevs) of chiral primary operators (CPOs) with conformal dimension one for the supersymmetric vacuum solusions in the mass-deformed ABJ (mABJ) theory, and compare it to dual quantities obtained by using the holographic method in 11-dimensional supergravity. In the large N limit, we show that the vevs are in exact agreement with the holographic quantities for all supersymmetric vacuum solutions. For LLM geometries with the discrete torsion, the holo-graphic results comprise 1 / N corrections. We also explore the effects of the orbifolding on the gauge/gravity duality dictionary and on the nature of the asymptotic limits of the LLM geometries. [ABSTRACT FROM AUTHOR]

In this study we compared the fluorescence emission of algal, river water/wastewater, and oil samples using a pulsed LED light source and an Ocean Optics Xenon Arc Lamp source. Light-emitting diodes (LED) had become an important light source in the field of fluorescence spectroscopy and Lamp type LEDs are cheap and can provide a narrow source of wavelength as compared to the continuous Xenon Arc lamp source. However, it is sensitive to static electricity and electrical power. If the LED is operated in pulsed mode, it can provide stable high intensity at a longer time. For the experiment, the operating modes of the three pulsed LED are 20mW, 50 µs at 500 Hz. For the river water samples, the fluorescence emission showed significant results at 500-nm. At 685-nm emission wavelength of the algal samples, the pulsed LED signal showed a positive correlation with the Xenon lamp. However, peak shifting was observed for the oil samples due to low excitation intensity observed. [ABSTRACT FROM AUTHOR]

In this paper, the double-Λ hypernuclei, H Λ Λ 6 e , H Λ Λ 5 e and H Λ Λ 5 e have been theoretically investigated to determine effective Λ-Λ interaction energies in double-Λ hypernuclei which is closely related to hyperon superfluidity in neutron stars. These double-Λ hypernuclei were considered as three-body cluster model; Λ-Λ-core nucleus. We constructed the free-space single-channel Λ-Λ interaction from Shinmura's multi-channel S=-2 potentials which are phase shift equivalent to Nijmegen soft core potentials. The interaction strength and range parameter are fitted with the most updated experimental data of Nagara event from E373 experiment. By using NSC97e potential, the effective Λ-Λ interaction energies are found to be 0.67 MeV, 0.88 MeV and 0.64 MeV for H Λ Λ 6 e , H Λ Λ 5 e and H Λ Λ 5 e respectively. The medium effects are not negligible in these double-Λ hypernuclei. [ABSTRACT FROM AUTHOR]

A technique to produce spin orientation in RI beams was developed for measurements of nuclear moments. The present scheme of two-step reaction realized highly spin-aligned RI beams for a wide range of exotic nuclei. Recently the two-step reaction scheme was applied to the magnetic moment measurement of an isomeric state of a neutron-rich nucleus 75Cu, where its magnetic moment was determined for the first time owing to a 30%-spin-aligned beam. A further perspective of the nuclear moment measurements employing the present scheme is expected. [ABSTRACT FROM AUTHOR]

We have studied the photoproduction of Λ(1405) from the CLAS Collaboration with a chiral dynamics model. The reaction γ + p → K + (π ∑) 0 was conducted for the wide range of photon energies 1.95 2 minimum for the calculated invariant mass spectra of CLAS data. The mass M and decay width Γ of the Λ(1405) resonance is deduced to be 1401.8 − 2.3 + 2.3 MeV / c 2 and 65.4 − 5.0 + 5.0 MeV respectively, from the interaction parameter set which provides the minimum χ2 fit spectrum.

Industrial computed tomography provides a means to non-destructively examine defects in concrete structures. CT images were obtained from gamma ray scans of several rebar imbedded concrete samples as well as scans of rectangular concrete pillars. The CT scanner consists of a clamped on mechanical gantry, a 1" x 1" NaI(Tl) scintillation detector, 0.4GBq Ba-133 source, 15mm x 5mm lead collimators and Ludlum scaler ratemeter. The purpose of this work was to provide baseline image structural information to detect anomalies and to check internal structural deviation in concrete-based pillars. Among possible causes of defects are poor concrete compaction, rebar congestion, and insufficient concrete strength. It is suggested that rich information from 2D CT images could help the engineer make the right decisions on the state of deterioration of building pillars. The images also provide direct evidence of presence of void, and rebar placement. Further works using the portable gamma ray CT scanner are expected to be used in non-invasive inspection for building restoration. [ABSTRACT FROM AUTHOR]

The Coulomb shift in the mirror systems of α +14C in 18O and α+14O in 18Ne is investigated by applying the orthogonality condition model (OCM). The result of OCM predicts the reduction of the excitation energies of the higher O+ states in the proton-rich nucleus of 18Ne in comparison to the energies in the neutron-rich 18O nucleus. This reduced excitation energy is similar to the phenomenon known as the Thomas-Ehrman shift, which means the lower shift in the excitation energy of the s-wave single particle orbit around the 16O core.

We have conducted theoretical study on a production reaction 16 O (K − , p) K − 15 C which populates kaonic nuclei C K − 15 (=15N-K− bound system). The main purpose of this study is to deduce the kaon-nucleus interaction from the present existing and future experimental observations of kaon-nuclear production through (K−, p) reaction with different targets. Our analysis using 16O target is the first step for our upcoming systematic study by employing wide range of targets. We have considered two models, namely K−pp and Λ*p models in our analysis to determine the formation mechanism of kaonic nucleus and find out the differences between the two models. We have investigated the missing mass spectrum for the above (K−, p) reaction by using Green's function method. The interaction between K− and nucleus is taken to be Woods-Saxon potential. We have analyzed the characteristic of the spectrum by varying the potential strengths as well as scattering angles by using the above two models. It is observed that a large component of quasi free K− is compatible with the Λ*p model. [ABSTRACT FROM AUTHOR]

The single-particle states are degenerate in the ground-state of an even-even nucleus since there are at least two states (corresponding to spin up and spin down) with the same energy. However, this is not the case for odd-mass nucleus due to the existence of the unpaired nucleon which breaks the time reversal symmetry. The impact of the time-reversal symmetry breaking on a wide range of rare earth nuclei has been investigated recently within the Skyrme mean-field approach using the Skyrme SIII parametrization [1]. In order to have a more complete assessment on the impact of time-reversal symmetry breaking on nuclear properties, we performed calculations using the SLy5* parametrization with BCS pairing. The seniority force is used to approximate the residual pairing interaction. In this work, some nuclear properties of odd-mass rare earth nuclei namely binding energy, nuclear charge radii, spectroscopic charge quadrupole moment and band-head energy spectra are compared to previous SIII calculations and experimental data.

We investigate the energy distribution of the isoscalar monopole and dipole transitions in the heavy systems, such as 44Ti and Te isotopes. The macroscopic α cluster models with α+40Ca and α+Sn are applied to 44Ti and Sn isotopes, respectively. The present calculation shows that the monopole and dipole strengths are strongly enhanced by the excitation in the the α cluster degrees of freedom. The discrete and sharp strength is generated by the α cluster excitation at the excitation energy much lower than the energy for the single nucleon excitation inside of the uniform mean field potential.

The proton's electric G E p (Q 2) and magnetic G M p (Q 2) form factors (FFs) are fundamental quantities in nuclear and elementary particle physics. However, the inconsistency in the results on these FFs and their ratio μ p R p = μ p G E p / G M p as measured using the conventional Rosenbluth separation method, and the polarization transfer (PT) method suggested a systematic difference between the two techniques. To reconcile these measurements, several studies suggested that missing higher order radiative correction to the electron-proton elastic scattering cross section σR(ε, Q2), and in particular two-photon exchange (TPE) corrections should be applied. While several analyses were performed to extract the TPE contributions, the most direct technique for measuring TPE is the comparison of electron-proton and positron-proton elastic scattering. In this study, I present a new extraction of the e± elastic scattering cross-section ratio Re+e− as determined using a new parametrization of the TPE corrections. I then compare my results to several previous phenomenological extractions, TPE hadronic calculations, and existing world data on the ratio Re+e− emphasizing mainly the recent high-Q2 measurements from the CLAS, VEPP-3 Novosibirsk, and OLYMPUS collaborations.

The Asian Nuclear Physics Association (ANPhA) is the central organization representing nuclear physics community in Asia Pacific. ANPhA is now preparing a list of accelerators applicable for nuclear physics experiments in Asia Pacific. Among the listed facilities, world-class "major" accelerator facilities are mainly located in China (Heavy Ion Research Facility in Lanzhou (HIRFL), and its future extension in Huizhou, i.e. HIAF/CiADS, Beijing Tandem Accelerator National Laboratory (BTANL), which is now upgraded to Beijing RI beam Facility (BRIF)), in Korea (RISP/RAON), and in Japan (RIBF at RIKEN, J-PARC, RCNP, and ELPH/LEPS). Characteristics of these "major" facilities including their developments will be briefly reviewed in comparing with similar ones in Europe and North America. [ABSTRACT FROM AUTHOR]

Using the dynamical cluster decay model (DCM), the fission dynamics of Z=120 superheavy nucleus formed via 64Ni+238U→302120∗ reaction is analyzed. The fission excitation functions and average total kinetic energy (TKE̅) distribution are addressed by including static as well as temperature-dependent (T-dependent) deformations. The cross-sections calculated using collective clusterization method find decent agrement with the available data. Beside this, the role of hot and cold optimum orientations is explored, which suggests the asymmetric mass distribution for head on collisions and symmetric fragmentation for pole-to-pole interactions of colliding nuclei.

KISS project aims at finding an astrophysical condition for synthesizing isotopes of heavy elements under a rapid neutron-capture (r)-process, which forms the third peak in the solar elemental abundance pattern. This is an experimental challenge in nuclear physics to measure nuclear properties of ground- and isomeric-states in unknown neutron-rich nuclei around the region of A=195 and N=126. So far, we have constructed and developed a new type of mass separation system, KISS (KEK Isotope Separation System) and performed measurements of lifetimes, decay schemes, and hyperfine structures of some platinum, iridium, and osmium isotopes by applying multi-nucleon transfer reactions, in-gas-cell laser ionization, and decay spectroscopic techniques. In this report, recent physics results and updated KISS performance are presented. In addition to the KISS activities, a newly launched project in WNSC is introduced. It concerns a comprehensive nuclear mass measurement with MRTOF (Multi-Reflection Time-Of-Flight mass-spectrograph). Some of MRTOF's have been installed not only at KISS but also at GAs-filled Recoil Ion Separator (GARIS II) of Riken RI-Beam Factory (RIBF), the latter of which is going to measure masses of superheavy isotopes.

Ordinary µ capture is useful for probing the neutrino nuclear responses for double beta decay especially in the β+ side region. The aim of this study is to measure the prompt and delayed gamma rays from NatMo (µ,xnv) and 100Mo (µ,xnv) reactions and calculate the relative capture strength, β(µ,E) using the Proton-Neutron Emission Model (PNEM). Experimental data of NatMo and 100Mo targets irradiated by negative µ at MuSIC Facility, Osaka University are analysed and the production rates, and the mass distribution were obtained. The experimental data was compared with the mass distribution calculation using PNEM to get the β(µ,E). The giant resonance (GR) like distribution was observed with the first GR peak around 12 MeV.

In this research, pionic energy spectra of hypertriton H Λ 3 and H Λ 4 weak decay process are investigated in the frame work of Plane Wave Impulse Approximation (PWIA). The pionic energy spectra from H Λ 3 and H Λ 4 weak decay process are obtained by using Green's function method. Interaction between deuteron d-Λ is constructed by fitting the parameters of Isle type potential with a central repulsion and a single Gaussian potential with no repulsion (SG) which H reproduce the binding energy of hypertriton H Λ 3 . We have analyzed in detail the antisymmetrization of H Λ 3 which is the H origin of enhancement in H Λ 3 decay rate. This might solve the discrepancy issue of H Λ 3 decay life time between theoretical and experimental results. Similar analysis for H Λ 4 hypernucleus was conducted. [ABSTRACT FROM AUTHOR]
