摘要

The spectroscopy of Se-76 has been studied using the Zn-70(C-12, alpha 2n) Se-76 fusion evaporation reaction. The yrast band of Se-76 has been extended to substantially higher spin, allowing observation of the second band crossing. The much-delayed g(9/2) 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 Se-76. Based on the systematic investigation of the band crossings associated with the g(9/2) 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.
