Abstract
gamma-ray decays depopulating isomeric states have been observed in a numbe r of very neutron deficient nuclei around A similar to 80 following the pro jectile fragmentation of a Mo-92 primary beam. Previously unobserved decays have been identified in the N = Z + 2 nuclei Y-80(39) and Nb-84(41) and th e N = Z nucleus, Tc-86(43), making the latter the heaviest N = Z nucleus to date in which a discrete gamma-ray transition has been assigned. The Lifet ime of the previously reported I-pi =9/2 + isomeric state in Kr-73 has also been measured and a clearer picture of its decay properties has been deduc ed. Isomeric ratios have been measured and have been interpreted in terms o f the yrast or nonyrast nature of the isomeric state.
