Abstract
Neutron deficient nuclei up to 100Sn were produced by fragmentation of a 1A·GeV 112Sn beam in a Be target. After isotopic separation by a fragment separator, the radionuclides were implanted in a stack of position sensitive Si-detectors acting as a microcalorimeter. The halflives and other decay properties were measured. Here we report halflives of rp-process waiting point nuclei between 80Zr and 92,93Pd. In addition the halflifes of the very short lived odd-odd NZ nuclei 90Rh, 94Ag and 98In were determined and attributed to superallowed Fermi transitions. Two new isotopes close to the p-dripline, 76Y and 78Zr, were identified for the first time.
