Half-life determination of Tz = -1 and Tz = -1/2 proton-rich nuclei and the decay of 58Zn

We have measured the β-decay half-lives of 16 neutron-deficient nuclei with Tz=−1/2 and −1, ranging from chromium to germanium. They were produced in an experiment carried out at GANIL and optimized for the production of 58Zn, for which in addition we present the decay scheme and absolute Fermi and Gamow-Teller transition strengths. Since all of these nuclei lie on the rp-process pathway, the T1/2 values are important ingredients for the rp-process reaction flow calculations and for models of X-ray bursters.
