Abstract

The decay properties of rp-process nuclei in the vicinity of ¹⁰⁰Sn have been studied at the National Superconducting Cyclotron Laboratory (NSCL). The measured β-decay half-life for ¹⁰⁰Sn is 0.55_-0.31^+0.70s, in agreement with a previous measurement. In ⁹⁸In, the β-decay of the ground state plus that of a long lived isomer were observed with half-lives of 47(13) ms and 0.66(40) s respectively. The half-life of ⁹⁶Cd, measured for the first time, is 1.03_-0.21^+0.24s; however, the existence of a predicted isomeric state in this nucleus could not be confirmed. Additionally, a gamma cascade de-exciting a μ-isomer in the odd-odd nucleus ⁹⁶Ag was observed. The implications of the measured half-life of ⁹⁶Cd on the calculated rp-process final abundances are discussed.
