【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 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.
