Abstract：
High-spin states in ¹⁰¹Pd have been investigated experimentally via the ⁷⁶Ge(²⁸Si, 3nγ)¹⁰¹Pd reaction. The previously known bands based on the d_5/2 and h_11/2 neutron 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.
