Abstract

Isomers in near-spherical Z=51, antimony isotopes are reported here for the first time using fusion-fission reactions between Al27 and a pulsed Hf178 beam of energy, 1150 MeV. γ rays were observed from the decay of isomeric states with half-lives, T1/2=200(30) and 52(3)μs, and angular momenta I=(252) and Iπ=232+, in Sb121,123, respectively. These states are proposed to correspond to ν(h112)2 configurations, coupled to an odd d52 or g72 proton. Nanosecond isomers were also identified at Iπ=192- [T1/2=8.5(5) ns] in Sb121 and Iπ=(152-) [T1/2=37(4) ns] in Sb123. Information on spins and parities of states in these nuclei was obtained using a combination of angular correlation and intensity-balance measurements. The configurations of states in these nuclei are discussed using a combination of spin/energy systematics and shell-model calculations for neighboring tin isotones and antimony isotopes.
