采用修正的表面δ相互作用（ＭＳＤＩ），对１０６Ｐｄ、１０８Ｐｄ、１１０Ｐｄ、１１２Ｐｄ、１１４Ｐｄ和１１６Ｐｄ等６个偶偶核做了形变ＨＦ计算．得到了长椭球、扁椭球和一些激发态的解．结果表明，在质量数为１０６到１１６间的原子核存在形状过渡，且单粒子能级随质量数及组态的不同而不同．同时，还用近似角动量投影形变Ｈａｒｔｒｅｅ－Ｆｏｃｋ（ＰＤＨＦ）方法对１１０Ｐｄ进行了能谱计算，其计算结果与实验谱基本一致，并且发现投影谱具有γ软性核谱的特征．
Deformed HF calculations were performed on six even-numbered nuclei such as 106Pd, 108Pd, 110Pd, 112Pd, 114Pd and 116Pd using the modified Surface δ Interaction (MSDI). The solutions of ellipsoids, oblate ellipsoids and some excited states are obtained. The results show that there is a transition in the shape of the nucleus with a mass of 106 to 116, and the single-particle energy level varies with the number of masses and the configuration. At the same time, the energy spectrum of 110Pd was also calculated by using approximate Hartree-Fock (PDHF) method. The calculated results are basically consistent with the experimental spectra, and the spectrum of γ-soft nuclei is also found.
