摘 要:采用修正的表面δ相互作用(MSDI),对116Xe,118Xe,122Xe,124Ba和126Ba五个偶偶核作了形变HF计算,得到长椭球、扁椭球和一些激发态的解.结果表明,在质量数为116~126的原子核间存在形状过渡,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122Xe,124Ba和126Ba进行了能谱计算,其计算结果与实验谱基本一致。The authors using modified surface delta interaction,the deformed HartreeFock calculations for the five nuclei:116Xe,118Xe,122Xe,124Ba and 126Ba are performed.The prolate,oblate and some particlehole excited configurations are obtained.The solutions of the results show that there is a form transition from mass number 116 to 126,and that singleparticle energy spectra are different not only for different mass mumber of the nuclei but also for different configuration.After that the approximate angular momentum projected HartreeFock (PDHF) method is used in nuclei 122Xe,124Ba and 126Ba.The results of calculating energy spectra are fit well with experiment spectra.It is found that the PDHF spectra have the properties of the γsoft nuclear spectra.
