摘要
采用修正的表面δ相互作用（MSDI），对102-114Ru、102-116Pd和104-116Cd等22个偶偶核作了形变HF计算．得到了长椭球、扁椭球等基态或激发态的解．结果表明，在质量数为102—116间的原子核存在形状过渡、形状共存现象，且单粒子能级随质量数及组态的不同而不同.同时发现质子数的多少以及3S1／2轨道的开始填充对形状过渡起着重要作用．
Using modified surface delta interaction, the deformed Hartree-Fock calculations for twenty tWo nuclei: 102-114 Ru, 102-116 Pd and 104-116 Cd are performed.Prolate and oblate configurations are obtained. The calculated results show that there exist form transitions and shape coexistence from mass number 102 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, it is also found that the numbers of proton and the 3s1/2 orbit begining to fill with neutrons play important roles in the shape transitions.
