Abstract
High-spin states in have been studied experimentally using the reaction at beam energies of 88 and 95 MeV. The level scheme of has been revised significantly and extended to high-spin states. Rotational bands have been analyzed in the framework of triaxial particle-rotor model, and a triaxial shape and a near-prolate shape have been proposed to the and bands, respectively. Two transition sequences with similar energies have been observed, and they have been proposed to be associated with the configuration. The structure built on the configuration could be interpreted as a pair of pseudospin partners. The level energies in the pseudospin partner bands are well reproduced by the theoretical calculations of the triaxial particle-rotor model if a near-oblate shape is assumed.
