摘要
采用修正的表面δ相互作用(MSDI),对106Pd、108Pd、110Pd、112Pd、114Pd和116Pd等6个偶偶核做了形变HF计算.得到了长椭球、扁椭球和一些激发态的解.结果表明,在质量数为106到116间的原子核存在形状过渡,且单粒子能级随质量数及组态的不同而不同.同时,还用近似角动量投影形变Hartree-Fock(PDHF)方法对110Pd进行了能谱计算,其计算结果与实验谱基本一致,并且发现投影谱具有γ软性核谱的特征.
By using modified surface delta interaction, the deformed Hartree Fock calculations are performed for the six nuclei: 106 Pd, 108 Pd, 110 Pd, 112 Pd, 114 Pd and 116 Pd. The prolate, oblate and some particle hole excited configurations are obtained.The calculated results show that there is a form transition from mass number 106 to 116, and that single particle energy spectra are different not only for the nuclei with different mass number but also for different configuration. The approximate angular momentum projected Hartree Fock (PDHF) method is applied to nuclei 110 Pd. The results of calculated energy spectra are in agreement well with experimental spectra. It is found that the PDHF spectra have the properties of the γ soft nuclear spectra.
