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 HartreeFock calculations for the five nuclei:116Xe,118Xe,122Xe,124Ba and 126Ba are performed.The prolate,oblate and some particlehole excited configurations are obtained.The solutions of the results show that there is a form transition from mass number 116 to 126,and that singleparticle 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 HartreeFock (PDHF) method is used in nuclei 122Xe,124Ba and  126Ba.The results of calculating energy spectra are fit well with experiment spectra.It is found that the PDHF spectra have the properties of the γsoft nuclear spectra.
