Abstract
High-spin states in Kr-76 were studied using the Fe-54(Si-28, alpha 2p ) reaction at 120 MeV. Two new level sequences with negative parity de caying to known states in Kr-76 have been identified from prompt gamma -gamma coincidences. The observed band crossings at a rotational frequ ency of about 0.55 MeV/HBAR can be understood as a g(9/2) quasiproton alignment in bands built on two-quasineutron excitations at near-prola te deformation, in contrast to the g(9/2) quasineutron alignment at ab out 0.75 MeV/HBAR in the previously known two-quasiproton negative-par ity bands.
