Abstract

High-spin states in [Formula Presented] were populated with the [Formula Presented] reaction at a beam energy of 184 MeV. The previously known ground-state band has been extended to [Formula Presented] and four sidebands were observed. Configuration assignments for these sidebands are discussed based on their alignment behavior. A significant delay of the [Formula Presented] crossing frequency is observed in the [Formula Presented] region, with the largest delays occurring consistently at [Formula Presented] Cranked shell model calculations were performed in order to investigate whether a variation of deformation and/or pairing parameters can account for this phenomenon.
