摘要
High-spin states in ^101Pd have been investigated experimentally via the ^76Ge（^28Si, ^3nγ）^101pd reaction. The previously known bands based on the d5/2 and h11/2 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 y rays deexciting the oriented states. For the ground-state band, the E-COS （E-Gamma Over Spin） curve strongly suggests a structure transition from vibration to rotation while increasing spin.
