Beta-Delayed Neutron Emission of N = 84 Cd 132
Year: 2026
Type: article
Abstract: Using the time-of-flight technique, we measured the beta-delayed neutron emission of ^{132}Cd. From our large-scale shell model (LSSM) calculation using the N^{3}LO interaction [Z. Y. Xu et al., Phys. Rev. Lett. 131, 022501 (2023)PRLTAO0031-900710.1103/PhysRevLett.131.022501], we suggest the decay is dominated by the transformation of a neutron in the g_{7/2} orbital, deep below the Fermi surface, into a proton in the g_{9/2} orbital. We compare the beta-decay half-lives and neutron branching ratios of nuclei with Z<50 and N≥82 obtained with our LSSM with those of leading "global" models such as finite-range droplet model (FRDM). Our calculations match known half-lives and neutron branching ratios well and suggest that current leading models overestimate the yet-to-be-measured half-lives. Our model, backed by the ^{132}Cd decay data presented here, offers robust predictive power for nuclei of astrophysical interest such as r-process waiting points.
