摘要: 将具有负宇称的 fp 空间扩大到包含1g9/2 轨道, 采用修正的表面相互作用(MSDI), 对64Ge, 66Ge, 68Ge, 70Se, 72Se, 74Se, 76Kr 和 78Kr等偶偶核作了形变HartreeFock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HartreeFock(PDHF)方法对偶偶核64Ge, 74Se和奇A核79Kr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 fp configuration space to include the 1g9/2 orbit with the abnormalparity, the deformed HartreeFock calculations for the eight nuclei: 64Ge, 66Ge, 68Ge, 70Se, 72Se , 74Se, 76Kr and 78Kr are performed. The groundstate and some particlehole excited configurations are obtained. The approximate angular momentum projected deformed HartreeFock (PDHF) method is applied to even even nuclei 64Ge and 74Se and oddA nuclus 79Kr. Both of their normal and abnormalparity bands are obtained. The calculated energy spectra are consistent well with experimental spectra.Abstract: Using modified surface delta interaction, enlarging the fp configuration space to include the 1g9/2 orbit with the abnormalparity, the deformed HartreeFock calculations for the eight nuclei: 64Ge, 66Ge, 68Ge, 70Se, 72Se , 74Se, 76Kr and 78Kr are performed.
