摘要
将具有正宇称的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10 4 Cd ,10 6Cd ,10 8Cd ,110 Cd ,112 Cd ,114 Cd和116Cd等 7个偶偶核作了形变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10 8Cd和110 Cd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 1h 11/2 states with the negative-parity,the deformed Hartree-Fock calculations for the seven nuclei ( 104Cd, 106Cd, 108Cd, 110Cd, 112Cd, 114Cd and 116Cd) are performed. The ground-state and some particle-hole excited configurations are obtained. The calculated results show that there exist form transition and shape coexistence from mass number 104 to 116,and that the single-particle energy spectra are different not only for different mass number but also for different configurations of nuclei. At the same time,the approximate angular momentum projected Hartree-Fock(PDHF) method is applied to nuclei 108Cd and 110Cd. And both of their positive- and negative-parity bands are obtained. The results of calculated energy spectra are consistent with experimental spectra well.
