Abstract
High-spin states in have been investigated with the reaction O,xnCd at beam energies of 60 and 70 MeV. The decoupled yrast bands observed in both nuclei are interpreted as being built upon a low-Kh11/2-quasineutron configuration. Both structures exhibit band crossings corresponding to the rotational alignment of a pair of h11/2 quasineutrons. Two positive-parity bands built on a g7/2-quasineutron configuration are observed in . These exhibit a signature inversion in the region of the first (ν alignment. This may be associated with some softness to triaxiality. The results are discussed in terms of the cranked shell model, total Routhian surface calculations, and the systematics of neighboring nuclei.
