偶偶Cd同位素核的负宇称带研究
Studies on The Negative Parity Bands of Even Even Cd Nuclei
【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.
【Abstract】 Using modified surface delta interaction, enlarging the gds configuration space to include the states with the negativeparity, the deformed HartreeFock calculations for the both nuclei: 106Cd and 108Cd are performed. The groundstate and some particlehole excited configurations are obtained. The approximate angular momentum projected HartreeFock (PDHF) method is applied to nuclei 106Cd and 108Cd.Both of their positive and negativeparity bands are obtained.The calculated energy spectra are consistent with experimental spectra well.
【Key words】 angular momentum projection; single-particle energy spectra; negative-parity band;
