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 the modified surface δ-interaction (MSDI), deforming HF calculations were performed on 22 even-numbered nuclei such as 102-114Ru, 102-116Pd and 104-116Cd. The solutions of ground state or excited state such as ellipsoid and oblate ellipsoid are obtained. The results show that there are transitions and shapes coexisting in nuclei with mass numbers of 102-116, and the energy levels of single particles vary with the number of masses and the configurations. Meanwhile, the number of protons and the beginning of 3S1 / 2 orbit Filling plays an important role in shaping the transition.
