“…This value agrees with e n = 0.8 as adopted by Teruya et al [19] for N = 130. [36], which implies a smaller effective charge of e n = 0.46 (1). The wavefunctions of the 8 + 1 and 10 + 1 states in Sn are more complex than in 130 Sn so the theoretical uncertainty might exceed the experimental uncertainty quoted for this effective charge.…”

“…The nine "stable" isotopes of Xe (A = 124, 126, 128, 129, 130, 131, 132, 134, 136) span a transitional region of nuclear structure that has yet to be fully characterized. While the light-mass isotopes appear to be gamma-soft rotors [1] and 136 Xe at the closed N = 82 shell exhibits seniority structure [2], the nature of those in between is not well understood. Certainly, collectivity is emerging as the number of neutron holes increases away from 136 Xe.…”

Inelastic neutron scattering was used to study the low-lying nuclear structure of 132 Xe. A comprehensive level scheme is presented, as well as new level lifetimes, multipole mixing ratios, branching ratios, and transition probabilities. Comparisons of these data as well as previously measured E2 strengths and g factors are made with new shell-model calculations for 132,134,136 Xe to explore the emergence of collectivity in the Xe isotopes with N < 82 near the closed shell. *

Probing the structure of the stable Xe isotopes with inelastic neutron scattering

The stable isotopes of xenon, which have attracted interest for a number of reasons, span a transitional region that evolves from γ-soft structures for the lighter mass isotopes to nearly spherical 136Xe with a closed neutron shell. The nature of this transition, which is gradual, is not well understood. To provide detailed spectroscopic information on the Xe isotopes, we have studied 130,132,134,136Xe at the University of Kentucky Accelerator Laboratory using inelastic neutron scattering and γ-ray detection. These measurements yielded γ-ray angular distributions, branching ratios, multipole mixing ratios, and level lifetimes (from the Doppler-shift attenuation method), which allowed the determination of reduced transition probabilities and provided insight into the structure of these nuclei.

“…Thus, two-nucleon transfer reactions provide a tool to identify pairing excitations, and a number of pairing vibrational states have been observed in heavier nuclei, e.g. the proton pairing vibrational states with excitation energy: 5.24 MeV in 208 Pb [11,12], 4.1 MeV in 206 Pb [12], 1.690 MeV in 124 Xe, 1.761 MeV in 126 Xe [13,14].…”

The quadrupole collective Hamiltonian, based on relativistic energy density functionals, is extended to include a pairing collective coordinate. In addition to quadrupole shape vibrations and rotations, the model describes pairing vibrations and the coupling between shape and pairing degrees of freedom. The parameters of the collective Hamiltonian are determined by constrained self-consistent relativistic mean-field plus Bardeen-Cooper-Schrieffer (RMF+BCS) calculations in the space of intrinsic shape and pairing deformations. The effect of coupling between shape and pairing degrees of freedom is analyzed in a study of low-energy spectra and transition rates of four axially symmetric N = 92 rare-earth isotones. When compared to results obtained with the standard quadrupole collective Hamiltonian, the inclusion of dynamical pairing increases the moment of inertia, lowers the energies of excited 0 + states and reduces the E0-transition strengths, in better agreement with data.
