Abstract

Coulomb-excitation experiments to study electromagnetic properties of radioactive even-even Hg isotopes were performed with 2.85 MeV/nucleon mercury beams from REX-ISOLDE. Magnitudes and relative signs of the reduced E2 matrix elements that couple the ground state and low-lying excited states in Hg182-188 were extracted. Information on the deformation of the ground and the first excited 0+ states was deduced using the quadrupole sum rules approach. Results show that the ground state is slightly deformed and of oblate nature, while a larger deformation for the excited 0+ state was noted in Hg182,184. The results are compared to beyond mean field and interacting-boson based models and interpreted within a two-state mixing model. Partial agreement with the model calculations was obtained. The presence of two different structures in the light even-mass mercury isotopes that coexist at low excitation energy is firmly established. ispartof: PHYSICAL REVIEW LETTERS vol:112 issue:16 ispartof: location:United States status: published

Abstract

International audience; A smooth onset of collectivity in Kr-88,Kr-92,Kr-94,Kr-96 has been determined from reported B(E2; 2(1)(+) -> 0(1)(+)) and E(2(1)(+)) values. This is in contrast to the sudden onset in even-even Zr, Mo, and Sr isotopes. Our objective was to complete the systematics by determining the B(E2; 2(1)(+) -> 0(1)(+)) value in Kr-90, which was produced by cold-neutron-induced fission of U-235. The lifetime of the 2(1)(+) state in Kr-90 was measured via the electronic gamma-gamma timing technique using the EXILL and FATIMA spectrometers. Based on themeasured mean lifetime of tau = 15(10) ps, the B(E2; 2(1)(+) -> 0(1)(+)) value of 13(-5)(+26) W.u. in Kr-90 is determined for the first time and the smooth onset of deformation in the even-even Kr isotopes beyond neutron number N = 50 is confirmed.

259. Neutron configurations in 113Pd

Abstract

Excited states in 113Pd, populated in β− decay of 113Rh and in spontaneous fission of 248Cm and 252Cf, have been studied by means of γ spectroscopy at the IGISOL facility of Jyvaskylä University and using large arrays of Ge detectors (Eurogam2 and Gammasphere, respectively). The position of the 11/2− yrast excitation in 113Pd, proposed recently at 166.1 keV by other authors, has been corrected to 98.9 keV. The decay of this level has been discussed to explain the observed transition intensities. The 7/2− member of the yrast, unique-parity configuration has been identified at 84.9 keV and a band on top of this level proposed. On top of the 1/2+, first excited state a band has been built and a new 3/2+ bandhead has been proposed at 151.9 keV. A possible oblate-shape origin of these low-energy bandsheads has been discussed. peerReviewed

Abstract

Single-neutron states in the Z = 30, N = 49 isotope Zn-79 have been populated using the Zn-78(d,p)Zn-79 transfer reaction at REX-ISOLDE, CERN. The experimental setup allowed the combined detection of protons ejected in the reaction, and of y rays emitted by Zn-79. The analysis reveals that the lowest excited states populated in the reaction lie at approximately 1 MeV of excitation, and involve neutron orbits above the N = 50 shell gap. From the analysis of gamma-ray data and of proton angular distributions, characteristic of the amount of angular momentum transferred, a 5/2+ configuration was assigned to a state at 983 keV. Comparison with large-scale-shell-model calculations supports a robust neutron N = 50 shell-closure for Ni-78. These data constitute an important step towards the understanding of the magicity of 78Ni and of the structure of nuclei in the region. (C) 2014 The Authors. Published by Elsevier B.V.
