摘　　要：本文采用相互作用玻色子模型研究了1 1 0 Pd 核的低能激发态的能谱和电磁跃迁 ,应用简化的哈密顿量很好的描述它们的能谱和跃迁过渡 .结果表明 ,1 1 0 Pd 基本上是属于U( 5)→O( 6)动力学对称的过渡核 ,同时也发现它具有SU( 3)对称性的明显特征 .The positive parity collective state and electromagnetic transition in the 110 P d are studied in the framework of the Interacting boson model.A schematic hamiltonian able to describe its spectra and electromagnetic transition.It is found that the spectra can be well described by the transition from vibration to r unstable rotor.In the meantime,the behavior of SU(3)dynamical symmetry is found in 110 P d.
