Abstract

High-spin states in ¹⁰¹Pd have been investigated by means of in-beam γ-ray spectroscopic techniques via the ⁷⁶Ge(²⁸Si, 3n) reaction at beam energies of 85 and 95 MeV. The previously known d _5/2 and 1/2⁻[550] bands were extended to higher spins, and the unfavored signature branch of the 1/2⁻[550] band was built. The band crossings observed experimentally are explained by the alignment of g _9/2 protons. The band properties in ¹⁰¹Pd are compared with those in the neighboring nuclei and are discussed within the framework of the cranked shell model (CSM).
