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

Abstract

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.
