摘　　要：作者将具有正宇称的gds轨道空间扩大到包含具有负宇称的1h11/2轨道,采用修正的表面δ相互作用(MSDI),对106Cd和108Cd两个偶偶核作了形变Hatree Fock(HF)计算,得到了基态和一些激发态的解.同时,还用近似角动量投影形变Hartree Fock(PDHF)方法,对106Cd和108Cd进行了能谱计算,得到其正、负宇称带的解,计算结果与实验谱基本一致.Using modified surface delta interaction, enlarging the gds configuration space to include the states with the negativeparity, the deformed HartreeFock calculations for the both nuclei: 106Cd and 108Cd are performed. The groundstate and some particlehole excited configurations are obtained. The approximate angular momentum projected HartreeFock (PDHF) method is applied to nuclei 106Cd and 108Cd.Both of their positive and negativeparity bands are obtained.The calculated energy spectra are consistent with experimental spectra well.
