Abstract
The decay half-lives of 22 neutron-deficient nuclei in the cobalt-to-krypton region have been measured following the fragmentation of a primary beam at an energy of 73 MeV per nucleon. The half-lives of the nuclei and are determined for the first time with values of (129±35) ms, and (33±12) ms, respectively. The impact of these results on the nucleosynthesis and time scale of the astrophysical rapid proton-capture process are discussed.
