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+0.70 s, 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+0.24 s; 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.
