- Abstract
Prompt and delayed γ-ray spectroscopy of the neutron-deficient, semi-magic isotope $^{187}$Pb has been performed using the recoil-decay and isomer-decay tagging techniques at the Argonne Gas-Filled Analyzer. A new 5.15(15)-μs isomeric state at only 308 keV above the spherical 3/2$^{−}$ ground state is identified and classified as a shape isomer. A strongly-coupled band is observed on top of the isomer, which is nearly identical to the one built on the prolate 7/2$^{−}$[514] Nilsson state in the isotone $^{185}$Hg. Based on this similarity and on the result of the potential-energy surface calculations, the new isomer in $^{187}$Pb is proposed to originate from the same configuration. The retarded character of the 308-keV (7/2$^{−}$)→3/2gs− transition with a deduced B(E2)=5.6(2)×10−4 W.u. can be well explained by the significant difference between the prolate parent and spherical daughter configurations, leading to the shape isomerism. The excitation energy of the isomer is surprisingly low, being roughly half of the excitation energies of the known 0$^{+}$ intruder bandheads in the neighboring $^{186,188}$Pb isotopes. The combined results of the present work and the previous α-decay and laser spectroscopy studies present evidence for triple shape coexistence at low energy in the negative-parity configurations of $^{187}$Pb, which is well reproduced by the potential-energy surface calculations.

- Abstract
The decay of the 13/2$^{+}$ isomeric state in $^{183}$Hg was observed for the first time following the α decay of the 13/2$^{+}$ isomer in $^{187}$Pb produced in the $^{142}$Nd($^{50}$Cr, 2p3n) reaction. Using α−γ delayed coincidence measurements, the half-life of this isomer was measured to be 290(30) μs. This isomer is proposed to deexcite by an unobserved low-energy M2 transition to the known 9/2$^{−}$ member of a strongly prolate-deformed 7/2$^{−}$[514] band, followed by a 105-keV M1 transition to the bandhead. A lower limit of B(M2) ≥ 0.018 W.u. was deduced for the unobserved transition. The presumed retardation is proposed to be due to the notable shape change between the initial, nearly spherical, and the final, strongly deformed, states. A similar scenario is also considered for the 13/2$^{+}$ isomer in $^{181}$Hg, suggesting both are cases of shape isomers. The B(M2) systematics of neutron transitions across the nuclear chart is discussed.

[PHYS.NUCL]Physics [physics]/Nuclear Theory [nucl-th] - Abstract
International audience; The neutron-deficient Bi188 and Po188 isotopes have been studied by γ-ray spectroscopy using the recoil-decay tagging technique with the Argonne Gas-Filled Analyzer. A new 0.25(5)-μs isomeric state and a prompt cascade formed by 319-, 366-, and 462-keV γ rays have been established on top of the (10−) α-decaying isomer in Bi188. The first excited (2+) state in Po188 was identified, its excitation energy of 242(2) keV continues the nearly constant trend for the first 2+ states in Po190,192,194. The state is most likely a member of a prolate rotational band built on the ground state, albeit mixing with other coexisting configurations cannot be excluded. The new results obtained in the present work provide new information to shape coexistence in bismuth and polonium isotopes near the neutron midshell at N=104. In this mass region, a reduction in the prompt γ-ray yield obtained with recoil decay tagging was observed for a few nuclides, and the possible reasons are presented.

- Abstract
Fine structure in the α decay of $^{223}$U was observed in the fusion-evaporation reaction $^{187}$Re($^{40}$Ar, p3n) by using fast digital pulse processing technique. Two α-decay branches of $^{223}$U feeding the ground state and 244 keV excited state of $^{219}$Th were identified by establishing the decay chain $^{223}$U →α1 $^{219}$Th →α2 $^{215}$Ra →α3 $^{211}$Rn. The α-particle energy for the ground-state to ground-state transition of $^{223}$U was determined to be 8993(17) keV, 213 keV higher than the previous value, the half-life was updated to be 62−10+14 μs. Evolution of nuclear structure for N = 131 even-Z isotones from Po to U was discussed in the frameworks of nuclear mass and reduced α-decay width, a weakening octupole deformation in the ground state of $^{223}$U relative to its lighter isotones $^{219}$Ra and $^{221}$Th was suggested.

Rapid improvements in the hardware and software for geographic information system (GIS) have enhanced its potential for solving various types of engineering and management problems. This study develops a multiobjective, mixed-integer programming model for collection vehicle routing and scheduling for solid waste management systems synthesized within a GIS environment. The integration of the mathematical programming model and the GIS were demonstrated through application to a specific site in Taiwan. The proposed interactive design procedure using GIS allows a decision maker to analyze many waste collection alternatives before selecting a final operational scenario. Such a system also has potential application in many other environmental planning and management problems.

Excited states in $^{63,65,67}$Mn were studied via in-beam γ-ray spectroscopy following knockout reactions from $^{68}$Fe. Similar level schemes, consisting of the 11/2$^{−}$, 9/2$^{−}$, 7/2$^{−}$ and 5/2g.s.− level sequence, connected by I→I−1 transitions, were established, the first time for $^{65,67}$Mn. Their level structures show features consistent with strongly-coupled rotational bands with K=5/2. State-of-the-art shell-model calculations with the modified LNPS effective interaction reproduce the observed levels remarkably well and suggest the dominance of 4-particle-4-hole neutron configurations for all the states. The data on the low-lying excited states of odd-mass $^{53−67}$Mn provide a textbook example of nuclear structure evolution from weak coupling through decoupling to strong coupling along a single isotopic chain on the n-rich side of the β stability line. These results help to deepen our understanding of the N=40 “island of inversion”.

International audience; The photoproduction of ω mesons off the proton has been studied in the reaction γp→pω using the CEBAF Large Acceptance Spectrometer (CLAS) and the frozen-spin target in Hall B at the Thomas Jefferson National Accelerator Facility. For the first time, the target asymmetry T has been measured in photoproduction from the decay ω→π+π−π0, using a transversely polarized target with energies ranging from just above the reaction threshold up to 2.8 GeV. Significant nonzero values are observed for these asymmetries, reaching about 30–40% in the third-resonance region. New measurements for the photon-beam asymmetry Σ are also presented, which agree well with previous CLAS results and extend the world database up to 2.1 GeV. These data and additional ω photoproduction observables from CLAS were included in a partial-wave analysis within the Bonn-Gatchina framework. Significant contributions from s-channel resonance production were found in addition to t-channel exchange processes.

The photoproduction of $\omega$ mesons off the proton has been studied in the reaction $\gamma p\to p\,\omega$ using the CEBAF Large Acceptance Spectrometer (CLAS) and the frozen-spin target (FROST) in Hall B at the Thomas Jefferson National Accelerator Facility. For the first time, the target asymmetry, $T$, has been measured in photoproduction from the decay $\omega\to\pi^+\pi^-\pi^0$, using a transversely-polarized target with energies ranging from just above the reaction threshold up to 2.8 GeV. Significant non-zero values are observed for these asymmetries, reaching about 30-40% in the third-resonance region. New measurements for the photon-beam asymmetry, $\Sigma$, are also presented, which agree well with previous CLAS results and extend the world database up to 2.1 GeV. These data and additional $\omega$-photoproduction observables from CLAS were included in a partial-wave analysis within the Bonn-Gatchina framework.

- Abstract
The N=130 short-lived isotope 223Np was produced as evaporation residue (ER) in the fusion reaction 40Ar + 187Re at the gas-filled recoil separator Spectrometer for Heavy Atom and Nuclear Structure (SHANS). It was identified through temporal and spatial correlations with α decays of 215Ac and/or 211Fr, the third and fourth members of the α-decay chain starting from 223Np. The pileup signals of ER(223Np)–α(223Np)–α(219Pa) were resolved by using the digital pulse processing technique. An α decay with half-life of T1/2=2.15(52100) μs and energy of Eα=9477(44)keV was attributed to 223Np. Spin and parity of 9/2− were tentatively proposed for the ground state of 223Np by combining the reduced α-decay width and large-scale shell-model calculations. This assignment together with the proton separation energy disprove the existence of a Z=92 subshell closure.

- Abstract
Excited states have been observed for the first time in the neutron-deficient nucleus Ba117 using the recoil-decay tagging technique following the heavy-ion fusion-evaporation reaction Zn64(Ni58, 2p3n)Ba117. Prompt γ rays have been assigned to Ba117 through correlations with β-delayed protons following the decay of A=117 recoils. Through the analysis of the γ-γ coincidence relationships, a high-spin level scheme consisting of two bands has been established in Ba117. Based on the systematics of the level spacings in the neighboring barium isotopes, the two bands are proposed to have νh11/2[532]5/2- and νd5/2[413]5/2+ configurations, respectively. The observed band-crossing properties are interpreted in the framework of cranked shell model.

International audience; We report the first measurement of differential and total cross sections for the γd→K0Λ(p) reaction, using data from the CLAS detector at the Thomas Jefferson National Accelerator Facility. Data collected during two separate experimental runs were studied with photon-energy coverage 0.8–3.6 GeV and 0.5– 2.6 GeV, respectively. The two measurements are consistent giving confidence in the method and determination of systematic uncertainties. The cross sections are compared with predictions from the KAON-MAID theoretical model (without kaon exchange), which deviate from the data at higher W and at forward kaon angles. These data, along with previously published cross sections for K+Λ photoproduction, provide essential constraints on the nucleon resonance spectrum. A first partial wave analysis was performed that describes the data without the introduction of new resonances.

Nuclear Experiment - Abstract
Background: Measurements of polarization observables for the reactions γ⃗ p→K+Λ and γ⃗ p→K+Σ0 have been performed. This is part of a program of measurements designed to study the spectrum of baryon resonances in particular, and nonperturbative QCD in general.\ud Purpose: The accurate measurement of several polarization observables provides tight constraints for phenomenological fits, which allow the study of strangeness in nucleon and nuclear systems. Beam-recoil observables for the γ⃗ p→K+Σ0 reaction have not been reported before now.\ud Method: The measurements were carried out using linearly polarized photon beams incident on a liquid hydrogen target, and the CLAS detector at the Thomas Jefferson National Accelerator Facility. The energy range of the results is 1.71

First results from the longitudinally polarized frozen-spin target (FROST) program are reported. The double-polarization observable E , for the reaction View the MathML source, has been measured using a circularly polarized tagged-photon beam, with energies from 0.35 to 2.37 GeV. The final-state pions were detected with the CEBAF Large Acceptance Spectrometer in Hall B at the Thomas Jefferson National Accelerator Facility. These polarization data agree fairly well with previous partial-wave analyses at low photon energies. Over much of the covered energy range, however, significant deviations are observed, particularly in the high-energy region where high-L multipoles contribute. The data have been included in new multipole analyses resulting in updated nucleon resonance parameters. We report updated fits from the Bonn–Gatchina, Jülich–Bonn, and SAID groups.

[PHYS.NEXP]Physics [physics]/Nuclear Experiment [nucl-ex] ,Nuclear Experiment - Abstract
Differential cross sections of the exclusive process $e p \to e^\prime \pi^+ n$ were measured with good precision in the range of the photon virtuality $Q^2 = 1.8 - 4.5$ GeV$^2$, and the invariant mass range of the $\pi^+ n$ final state W = 1.6 - 2.0 GeV using the CEBAF Large Acceptance Spectrometer. Data were collected with nearly complete coverage in the azimuthal and polar angles of the $n\pi^+$ center-of-mass system. More than 37,000 cross section points were measured. The contributions of the isospin $I = {1\over 2}$ resonances $N(1675){5\over 2}^-$, $N(1680){5\over 2}^+$ and $N(1710){1\over 2}^+$ were extracted at different values of $Q^2$ using a single-channel, energy-dependent resonance amplitude analysis. Two different approaches, the unitary isobar model and the fixed-$t$ dispersion relations, were employed in the analysis. We observe significant strength of the $N(1675){5\over 2}^-$ in the $A_{1/2}$ amplitude, which is in strong disagreement with quark models that predict both transverse amplitudes to be strongly suppressed. For the $N(1680){5\over 2}^+$ we observe a slow changeover from the dominance of the $A_{3/2}$ amplitude at the real photon point ($Q^2=0$) to a $Q^2$ where $A_{1/2}$ begins to dominate. The scalar amplitude $S_{1/2}$ drops rapidly with $Q^2$ consistent with quark model prediction. For the $N(1710){1\over 2}^+$ resonance our analysis shows significant strength for the $A_{1/2}$ amplitude at $Q^2 < 2.5$ GeV$^2$., Comment: 24 pages, 22 figures. arXiv admin note: substantial text overlap with arXiv:0709.1946

- Abstract
Lonicera confusa(LC) and Astragali Radix (AR) extracts have been shown to have antioxidant and anti-inflammatory activities in human. To determine whether LC or/and AR extracts had similar functions to improve the egg production and egg quality, 1,440 (52-wk-old) Lohmann pink-shell hens were randomly distributed into 4 treatments with nine replicates of 40 hens. The hens were fed a basal diet (CON) or the basal diet supplemented with 0.1% LC extracts, 0.1% AR extracts, or 0.1% LC extracts plus 0.1% AR extracts (LC-AR) for 12 wk. The eggs were collected on week 6 and 12 for analysis, and the plasma and ovaries were collected at end of trial. Dietary treatment did not influence (P< 0.05) egg production, egg weight, and feed conversion ratio. However, LC-AR addition increased (P< 0.02) yolk color and sensory quality of hard-boiled eggs compared to other groups. The LC-AR supplementation increased (P= 0.02), and LC addition tended to increase (P= 0.08) Haugh unit of eggs on week 12 compared to CON. The LC-AR supplementation decreased (P< 0.001), and LC or AR individual addition tended to decrease (P< 0.10) plasma malondialdehyde concentration compared to CON. Conversely, LC supplementation increased (P= 0.02) total superoxide dismutase activity, and LC or/and AR supplementation increased the activities of manganese-containing superoxide dismutase (MnSOD) (P< 0.08) and glutathione peroxidase (GSH-Px) (P< 0.01) in plasma, and the mRNA abundance of MnSOD, GSH-Px1, and catalase in ovaries (P< 0.05) compared to CON. The LC or/and AR supplementation decreased the concentrations of interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α) in plasma (P< 0.05), and the mRNA abundance of IL-6 and TNF-α in ovaries (P< 0.04) compared to CON. These results suggested dietary inclusion of LC or/and AR improved the albumen quality, and a blend of LC and AR improved yolk color, which were associated with the enhancement of antioxidant capacity and the suppression of systemic inflammation in hens.

We measured the ratios of electroproduction cross-sections from a proton target for three exclusive meson-baryon final states: $\Lambda K^+$, $p\pi^0$, and $n\pi^+$, with the CLAS detector at Jefferson Lab. Using a simple model of quark hadronization we extract q-qbar creation probabilities for the first time in exclusive two-body production, in which only a single q-qbar pair is created. We observe a sizable suppression of strange quark-antiquark pairs compared to non-strange pairs, similar to that seen in high-energy production., Comment: 5pages, 2figures
