Emerging collectivity from the nuclear structure of Xe 132: Inelastic neutron scattering studies and shell-model calculations

Abstract

Inelastic neutron scattering was used to study the low-lying nuclear structure of Xe132. 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 Xe132,134,136 to explore the emergence of collectivity in the Xe isotopes with N<82 near the closed shell. © 2019 American Physical Society.
