Title: New insights into the nuclear structure in neutron-rich ^{112,114,115,116,117,118}Pd

Abstract

New level schemes of ^{112,114,115,116,117,118}Pd are established by means of γ-γ-γ, γ-γ-γ-γ and γ-γ(θ) measurements of prompt fission γ rays from ²⁵²Cf using the Gammasphere multidetector array. Spins/parities were assigned to levels based on γ-γ angular correlation measurements, level systematics and decay patterns. In the even-N isotopes ^112,114,116Pd, two sets of odd-parity bands were identified and extended with spins measured in each band. The oddparity bands with large level staggerings were interpreted as disturbed chirality with less pronounced triaxial deformations in the Pd isotopes than observed in the chiral symmetry breaking ^110,112Ru with maximum triaxiality. Onset of wobbling motion was identified from the sign of the signature splitting in the γ band of even-even ¹¹⁴Pd, and probably also in ¹¹⁶Pd. as first seen in the N = 68 isotone ¹¹²Ru. Maximal triaxiality in Ru and Pd isotopes is found to be reached for N = 68, ¹¹²Ru and ¹¹⁴Pd, 4 neutrons more than predicted in the theoretical calculations. The new data and TRS calculations allowed a systematic study of the band crossings in the even-N ^112,114,116Pd and odd-N ^115,117Pd isotopes. Here, we find a new overall, more complex shape evolution than previously proposed, now from triaxial prolate in ¹¹⁰Pd viamore »« less

New insights into the nuclear structure in neutron-rich 112,114,115,116,117,118Pd

Journal Article Luo, Y. X. ; Rasmussen, J. O. ; Hamilton, J. H. ; ... - Nuclear Physics. A

New level schemes of 112,114,115,116,117,118Pd are established by means of ?–?–??–?–?, ?–?–?–??–?–?–? and ?–?(0)?–?(0) measurements of prompt fission y rays from 252Cf using the Gammasphere multi-detector array. Spins/parities were assigned to levels based on ?–??–? angular correlation measurements, level systematics and decay patterns. In the even-N isotopes 112,114,116Pd, two sets of odd-parity bands were identified and extended with spins measured in each band. The odd-parity bands with large level staggerings were interpreted as disturbed chirality with less pronounced triaxial deformations in the Pd isotopes than observed in the chiral symmetry breaking 110,112Ru with maximum triaxiality.

Evidence for possible shape transitions in neutron-rich Ru isotopes: Spectroscopy of {sup 109,110,111,112}Ru

Journal Article Wu, C Y ; Hua, H ; Cline, D ; ... - Physical Review. C, Nuclear Physics

The spectroscopy of neutron-rich {sup 109,110,111,112}Ru nuclei was studied by measuring the prompt {gamma} rays that originate from fission fragments, produced by the {sup 238}U({alpha},f) fusion-fission reaction, in coincidence with the detection of both fragments. For {sup 109,111}Ru, both the negative-parity (h{sub 11/2} orbitals) and K=5/2 positive-parity (mainly g{sub 7/2} and d{sub 5/2} orbitals) bands were extended to substantially higher spin and excitation energy than known previously. The ground-state and {gamma}-vibrational bands of {sup 110,112}Ru also were extended to higher spin, allowing observation of the second band crossing at the rotational frequency of {approx_equal}450 keV in {sup 112}Ru, which ismore »« less

Collective Motions in A = 100-112 Nuclei

Journal Article Hamilton, J H ; Ramayya, A V ; Hwang, J K ; ... - AIP Conference Proceedings

With a very high statistics data set with 5.7x10{sup 11} triple and higher fold {gamma} coincidences from the spontaneous fission of {sup 252}Cf, a wealth of fascinating new collective motions in nuclei with A = 100-112 have been observed. Nothing was known previously about one- and two-phonon {gamma}-bands in odd-A nuclei. We discovered the first one-and two- phonon {gamma} vibrational bands in an odd N-even Z nucleus, {sup 105}Mo. The energies of the one- and two- phonon bands in {sup 104}Mo, {sup 105}Mo, {sup 106}Mo and {sup 108}Mo were recently studied and are remarkably similar in energies. The first chiralmore »« less

New effective interaction for f{sub 5}pg{sub 9}-shell nuclei

Journal Article Honma, M ; Otsuka, T ; RIKEN, Hirosawa, Wako-shi, Saitama 351-0198 ; ... - Physical Review. C, Nuclear Physics

We present a new effective interaction for shell-model calculations in the model space consisting of the single-particle orbits 1p{sub 3/2}, 0f{sub 5/2}, 1p{sub 1/2}, and 0g{sub 9/2}. Starting with a realistic interaction based on the Bonn-C potential, 133 two-body matrix elements and four single-particle energies are modified empirically so as to fit 400 experimental energy data out of 69 nuclei with mass numbers A=63{approx}96. The systematics of binding energies, electromagnetic moments and transitions, and low-lying energy levels are described. The soft Z=28 closed core is observed, in contrast to the stable N=50 shell closure. The new interaction is applied tomore »« less
