Physics ,QC1-999 - Abstract
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate CP violation and hence probe physics beyond the Standard Model of particle physics. Isotopes of both radon and radium have been identified as candidates for such measurements. Here, we have observed the low-lying quantum states in 224Rn and 226Rn by accelerating beams of these radioactive nuclei. We show that radon isotopes undergo octupole vibrations but do not possess static pear-shapes in their ground states. We conclude that radon atoms provide less favourable conditions for the enhancement of a measurable atomic electric-dipole moment.

Physics ,QC1-999 - Abstract
The multinucleon transfer reaction mechanism was employed to populate isotopes around the doubly-magic 208 Pb nucleus. We used an unstable 94 Rb beam on 208 Pb targets of different thickness. Transfer channels were studied via the fragment-γ and γ-γ coincidences, by using MINIBALL γ spectrometer coupled to a particle detector. Gamma transitions associated to the different Pb isotopes, populated by the neutron transfers, are discussed in terms of excitation energy and spin. Fragment angular distributions were extracted, andcompared with the reaction models.

Physics ,QC1-999 - Abstract
A new Radioactive Ion Beam (RIB) facility (SPES) is presently under construction at the Legnaro National Laboratories of INFN. The SPES facility is based on the ISOL method using an UCx Direct Target able to sustain a power of 8 kW. The primary proton beam is provided by a high current Cyclotron accelerator with energy of 35-70 MeV and a beam current of 0.2-0.7 mA. Neutron-rich radioactive ions are produced by proton induced fission on an Uranium target at an expected fission rate of the order of 1013 fissions per second. After ionization and selection the exotic isotopes are re-accelerated by the ALPI superconducting LINAC at energies of 10A MeV for masses in the region A=130 amu. The expected secondary beam rates are of the order of 107 - 109 pps. Aim of the SPES facility is to deliver high intensity radioactive ion beams of neutron rich nuclei for nuclear physics research as well as to be an interdisciplinary research centre for radio-isotopes production for medicine and for neutron beams.

Nuclear and High Energy Physics ,ddc:530 ,[PHYS.PHYS.PHYS-INS-DET]Physics [physics]/Physics [physics]/Instrumentation and Detectors [physics.ins-det] - Abstract
19 pags., 16 figs., 8 tabs., We present the design, prototype developments and test results of the new time-of-flight detector (ToFD) which is part of the R3B experimental setup at GSI and FAIR, Darmstadt, Germany. The ToFD detector is able to detect heavy-ion residues of all charges at relativistic energies with a relative energy precision σΔE/ ΔE of up to 1% and a time precision of up to 14 ps (sigma). Together with an elaborate particle-tracking system, the full identification of relativistic ions from hydrogen up to uranium in mass and nuclear charge is possible., This work received support from BMBF (05P19RFFN1, 05P15RDFN1, 05P19RDFN1) and HIC for FAIR.

- Abstract
This deliverable describes the design of the evolved 5G Service layer solutions, in its final form as being realised in the 5GZORRO platform. The document builds upon the structure and the contents of D3.1 where the preliminary architecture and design choices were presented. It is intended to be a standalone version of 5GZORRO Service layer solutions design, aligned with the final version of 5GZORRO architecture reported in WP2. In addition to WP3 components design, the document includes descriptions of major technology enablers used to design and realise the 5GZORRO Service layer solutions, showing why these concepts (the DLT and the AIOPs) were chosen and how they have been applied in 5GZORRO context, both for realizing 5G Service layer solutions of WP3 (Identity and Permissions, Governance, Marketplace, Cross-domain Analytics & Intelligence) and in a broader context of Zero-touch Service Management and Orchestration developed in WP4. This final version of 5G Service layer solutions design is informed by the implementation activites performed across WP3 and WP4 (organized as several goal-oriented software development teams) as well as by the integration and validation activities ongoing as part of WP5 (Validation through Use Cases). To summarize, this deliverable complements the final version of 5GZORRO architecture, providing deeper level of detail for components and services contributed by WP3 along with their internal design and interworkings that will be further detailed in the last deliverable of WP3, D3.2, with low level descriptions of the software prototypes of evolved 5G Service layer solutions., EC approval: 10/02/2023

- Abstract
The article deals with the interpretation of the phraseme [SKY and EARTH and WATER / SEA] for [ COSMOS] which occurs in the Old Norse poem Vǫluspá (3): it is argued for an interpretation of the phrase as a merism of structure [A + [B + C]], an analysis that finds support in the lexicon and phraseology of Latin, Greek, Hittite and Armenian, among others.

Lifetime Measurements - Abstract
Aydın, Sezgin ( Aksaray, Yazar ), Background: The nuclear shape is a macroscopic feature of an atomic nucleus that is sensitive to the underlying nuclear structure in terms of collectivity and the interaction between nucleons. Therefore, the evolution of nuclear shapes has attracted many theoretical and experimental nuclear structure studies. The structure of the A≈70, N≈Z nuclei, lying far from the stability line, is interesting because a particularly strong proton-neutron correlation may occur here due to the occupation of the same orbits by nucleons of both types. In this region, different particle configurations drive a nucleus towards various deformed shapes: prolate, oblate, octupole, or nonaxial. These nuclear shapes change rapidly with nucleon number and also with angular momentum. This is reflected by a presence of different structures (bands) of excited states which exhibit a broad range of lifetimes. Purpose: The aim of this paper is to determine lifetimes of some high-spin excited states in As69 and Ge66 nuclei to examine the shape evolution in these neutron-deficient nuclei. Methods: Lifetimes of high-spin states in As69 and Ge66 have been measured by using the Doppler-shift attenuation technique with the GASP and recoil filter detector setup at the Laboratori Nazionali di Legnaro. The nuclei of interest were produced in the S32(95MeV)+0.8mg/cm2 Ca40 fusion-evaporation reaction. The strongest reaction channels 3p and α2p led to the As69 and Ge66 final nuclei, respectively. Using γ-γ-recoil coincidences we were able to determine very short lifetimes (in the femtosecond range) in the residual nuclei of interest. Results: In As69, the extracted lifetimes are τ=72 (-32, +45) fs for the 33/2+ state at 7897 keV and τ

The multinucleon transfer reaction mechanism was employed to populate isotopes around the doubly-magic
208 Pb nucleus. We used an unstable94 Rb beam on208 Pb targets of different thickness. Transfer channels were studied via the fragment-γ and γ-γ coincidences, by using MINIBALL γ spectrometer coupled to a particle detector. Gamma transitions associated to the different Pb isotopes, populated by the neutron transfers, are discussed in terms of excitation energy and spin. Fragment angular distributions were extracted, andcompared with the reaction models. [ABSTRACT FROM AUTHOR]- Published

DIPOLE moments ,PARTICLE physics ,RADIOACTIVE nuclear beams ,QUANTUM states ,GROUND state (Quantum mechanics) - Abstract
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate CP violation and hence probe physics beyond the Standard Model of particle physics. Isotopes of both radon and radium have been identified as candidates for such measurements. Here, we have observed the low-lying quantum states in
224 Rn and226 Rn by accelerating beams of these radioactive nuclei. We show that radon isotopes undergo octupole vibrations but do not possess static pear-shapes in their ground states. We conclude that radon atoms provide less favourable conditions for the enhancement of a measurable atomic electric-dipole moment. [ABSTRACT FROM AUTHOR]- Published

During the past ten years, ECOS working group and users strongly supported the construction of a dedicated high-intensity stable-ion-beam facility in Europe, with energies at and above the Coulomb barrier as part of the Long-Range Plan of the Nuclear-Physics community. LINCE will be a multi-user facility dedicated to ECOS science: fundamental physics, astrophysics, nuclear structure and reaction dynamics. Applied research is foreseen in the fields of medical physics, aerospace and material sciences with energetic heavy ions. The facility will produce a wide range of ions, from protons (45 MeV) up to Uranium (8.5 MeV/u) with 1mA maximum beam intensity. A very compact linac has been designed by using a HV platform with a double-frequency ECR ion source, multi-harmonic buncher, an innovative CW RFQ design (1 ≤A/Q ≤ 7) and 26 accelerating cavities made of bulk niobium (β = 0.045, 0.077 and 0.15) working at 72.75 and 10⁹.125 MHz. This article gives an outline of the accelerator complex from the ion source to the experimental areas, and presents its research potential and the relevant physics instrumentation., Proceedings of the 5th Int.

This work describes new electronics for the EX-OGAM2 (HP-Ge detector array) and NEDA (BC501A-based neutron detector array). A new digitizing card with high resolution has been designed for gamma-ray and neutron spectroscopy experiments. The higher bandwidth requirement of the NEDA signals, together with the necessity for accuracy, require a high sampling rate in order to preserve the shape for real-time Pulse Shape Analysis (PSA).

Nuclear Theory ,Calculated ,Nuclear Reactions ,Deduced ,Measured - Abstract
The level structures of the N=50 83 As, 82 Ge, and 81 Ga isotones have been investigated by means of multi-nucleon transfer reactions. A first experiment was performed with the CLARA-PRISMA setup to identify these nuclei. A second experiment was carried out with the GASP array in order to deduce the ?-ray coincidence information. The results obtained on the high-spin states of such nuclei are used to test the stability of the N=50 shell closure in the region of 78 Ni (Z=28). The comparison of the experimental level schemes with the shell-model calculations yields an N=50 energy gap value of 4.7(3) MeV at Z=28. This value, in a good agreement with the prediction of the finite-range liquid-drop model as well as with the recent large-scale shell model calculations, does not support a weakening of the N=50 shell gap down to Z=28. © 2012 Elsevier B.V., Science and Technology Facilities Council

NUCLEAR structure , *GAMMA ray detectors - Abstract
Big Ge-arrays like Euroball or Gasp have been built with the main purpose of studying high angular momentum phenomena in nuclei. When coupled with ancillary detectors they became also excellent instruments to explore the properties of very exotic nuclei far from β-stability. A large fraction of the experiments has been therefore devoted to study both proton-rich and neutron-rich nuclei populated using stable beams provided by the Legnaro and Strasbourg accelerators. Nuclei lying close to the N=Z line are of particular interest being a laboratory where collective excitations as well as fundamental properties of the nuclear force can be tested, like isospin symmetry and isospin breaking terms, proton neutron pairing, dripline effects. Due to their special symmetry they allow to test nuclear models. An example is the impact of nuclear physics calculations on the predictions of the standard model of the electro-weak interaction which requires unitarity for the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Available data suggest that the CKM matrix fails the unitarity test, pointing to physics beyond the standard model. Since such result depends on corrections for nuclear isospin mixing which must be calculated for heavy N=Z nuclei it is very important to test experimentally the model predictions. The isospin mixing probability can be determined using isospin forbidden γ transitions. If the charge symmetry of the nuclear force is exact, in the limit of long wavelengths, the E1 transition operator is purely isovector and therefore E1 transitions are forbidden in N=Z nuclei between states of equal isospin and have equal strength in mirror nuclei. Failure of this symmetry rule due to the isospin non conserving Coulomb interaction can be experimentally observed as an apparent "induced isoscalar term" through the presence of forbidden E1 transitions. An alternative method to test isospin symmetry is based on the investigation of the electromagnetic decay properties... [ABSTRACT FROM AUTHOR]

The evolution of nuclear properties as a function of the neutron excess depends on how the shell structure changes. This evolution has consequences on the ground state properties and on the single-particle and collective excitations. Presently, our knowledge about the structure of nuclei is mostly limited to nuclei close to the valley of stability or nuclei with a deficiency of neutrons. Only recently the availability of beams of unstable ions has given access to unexplored regions of the nuclear chart, especially on the neutron-rich side. A complementary way to study the structure of neutron-rich nuclear systems is offered by the use of high intensity beams of stable ions and binary reactions. Multi-nucleon and deep-inelastic reactions are a powerful tool to populate medium- and high-spin states in moderately neutron-rich systems. In this article, I will discuss some selected examples studied using the novel experimental setup that combines the large acceptance magnetic spectrometer, PRISMA, and the high-efficiency γ-ray detection arrays, CLARA and AGATA. They show the high potential of such reaction mechanism for the study of the spectroscopic properties of neutron-rich nuclear systems. [ABSTRACT FROM AUTHOR]

De Angelis, Giacomo, thesis supervisor: Giacinti Baschetti, Marco, De Angelis, Giacomo, and thesis supervisor: Giacinti Baschetti, Marco
- Abstract
The volumetric system is a widely used experimental method for gas adsorption equilibrium measurements and for the determination of adsorption kinetics. A predictive model was developed in the gPROMS ProcessBuilder platform. Equations for mass and energy balance were implemented firstly for the description of a single-branch volumetric apparatus, and then for a differential (double-branched) system. The model was built starting from the simplest case (Isothermal and ideal gas behaviour) and subsequentially its complexity was increased in order to have a system which is able of describing an adsorption process in any operative conditions (non-isothermal system, non-linear equilibrium, real gas behaviour). The validation of the model was made through the assumption that all the complex systems must collapsed to the simplest one through the adjustment of the different parameters. In certain cases, the validation was done comparing the results obtained in the simulation with the one got from analytical solutions developed by other authors. In general, at the end of each section, a case study was analysed in order to underline what are the factors that can affect the kinetic of the process, providing also possible solution which can minimize these effects, that if not taken into account can lead to an incorrect interpretation of the data.

WOS: 000372866900001, The NEutron Detector Array (NEDA) project aims at the construction of a new high-efficiency compact neutron detector array to be coupled with large gamma-ray arrays such as AGATA. The application of NEDA ranges from its use as selective neutron multiplicity filter for fusion-evaporation reaction to a large solid angle neutron tagging device. In the present work, possible configurations for the NEDA coupled with the Neutron Wall for the early implementation with AGATA has been simulated, using Monte Carlo techniques, in order to evaluate their performance figures. The goal of this early NEDA implementation is to improve, with respect to previous instruments, efficiency and capability to select multiplicity for fusion-evaporation reaction channels in which 1, 2 or 3 neutrons are emitted. Each NEDA detector unit has the shape of a regular hexagonal prism with a volume of about 3.23 l and it is filled with the EJ301 liquid scintillator, that presents good neutron-gamma discrimination properties. The simulations have been performed using a fusion-evaporation event generator that has been validated with a set of experimental data obtained in the Ni-58 + Fe-56 reaction measured with the Neutron Wall detector array., MINECO, Spain [FPA2011-29854-C04, FPA2012-33650, FPA2014-57196-C5]; Generalitat Valenciana, Spain [PROMETEO/2010/101, PROMETEOII/2014/019]; European Regional Development Fund (FEDER) of European Commission; Swedish Research Council; Polish National Science Centre [801/N-COPIN/2010/0, UM0-2014/14/M/ST2/00738, UM0-2013/08/M/ST2/0025]; Scientific and Technological Council of Turkey [106T055, 114F473]; UK STFC [ST/L005727/1]; Science and Technology Facilities Council [ST/L005727/1, ST/L005735/1], This work was partially supported by MINECO, Spain, under the grants FPA2011-29854-C04, FPA2012-33650 and FPA2014-57196-C5, and Generalitat Valenciana, Spain, under the grants PROMETEO/2010/101 and PROMETEOII/2014/019, The European Regional Development Fund (FEDER) of European Commission, the Swedish Research Council, the Polish National Science Centre under contracts: 801/N-COPIN/2010/0 (COPIN/IN2P3 collaboration), UM0-2014/14/M/ST2/00738 (COPIN-INFN collaboration), UM0-2013/08/M/ST2/0025 (LEA-COPIGAL collaboration), the Scientific and Technological Council of Turkey (Proj. no. 106T055 and 114F473), and the UK STFC (ST/L005727/1).

18th IEEE-NPSS Real Time Conference (RT) on Computing Applications in Nuclear and Plasma Sciences -- JUN 11-15, 2012 -- Berkeley, CA, WOS: 000325827700015, This work describes new electronics for the EX-OGAM2 (HP-Ge detector array) and NEDA (BC501A-based neutron detector array). A new digitizing card with high resolution has been designed for gamma-ray and neutron spectroscopy experiments. The higher bandwidth requirement of the NEDA signals, together with the necessity for accuracy, require a high sampling rate in order to preserve the shape for real-time Pulse Shape Analysis (PSA). The PSA is of paramount importance for the NEDA to discriminate between neutrons and gamma-ray signals. Both high resolution and high speed parameters are often difficult to achieve in a single electronic unit. These constraints, together with the need to build new digitizing electronics to improve performance and flexibility of signal analysis in nuclear physics experiments, led to the development a new FADC mezzanine card. In this work, the design and development are described, including the characterization procedure and the preliminary measurement results., Generalitat Valenciana, Spain [PROMETEO/2010/101]; Swedish Research Council; Scientific and Technological Research Council of Turkey (TUBITAK); INFN, Italy; Spanish MINECO [AIC-D-2011-0746, FPA2011-29854, FPA2012-33560], This work was supported by the Generalitat Valenciana, Spain, under Grant PROMETEO/2010/101, the Swedish Research Council, and the Scientific and Technological Research Council of Turkey (TUBITAK).
