【摘要】 将具有正宇称的gds组态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101Pd和101Ru两个奇A核进行了形变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101Pd和101Ru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.

【Abstract】 Using modified delta interaction, enlarging the gds configuration space to include the 1h11/2 orbital with negativeparity, the deformed HartreeFock calculations for both nuclei: 101Pd and 101Ru are performed. Their groundstate and some excited configurations are obtained. The approximate angular momentum projected deform HartreeFock (PDHF) method is also applied to nuclei 101Pd and 101Ru, and both of their positive and negativeparity bands are obtained. The calculated energy spectra are consistent with experimental spectra well.
