Abstract：

High-spin states in¹⁰¹Pd have been investigated experimentally via the⁷⁶Ge(²⁸Si, 3nγ)¹⁰¹Pd reaction. The previously known bands based on thed_5/2andh_11/2neutron orbitals have been extended to higher-spin states, and two new structures have been observed. Spin and parity were assigned to the levels on the basis of the experimental results of the angular distribution of γ rays deexciting the oriented states. For the ground-state band, the E-GOS (E-Gamma Over Spin) curve strongly suggests a structure transition from vibration to rotation while increasing spin.
