Abstract

The spectroscopy of Se76 has been studied using the Zn70(C12, α2n)76Se fusion evaporation reaction. The yrast band of Se76 has been extended to substantially higher spin, allowing observation of the second band crossing. The much-delayed g9/2 proton-pair alignment is discussed in terms of the cranked shell model and most likely is caused by a shape transition from prolate to oblate along the yrast line occurring in Se76. Based on the systematic investigation of the band crossings associated with the g9/2 quasiparticle alignments and their relationships with the shape evolutions in the even-A Se and Kr isotopes, a comprehensive picture of shape evolution along with spin and isospin in these nuclei is obtained.
