摘　　要：用｛ｃ，ｈ，ａ｝三参数旋转体模型描述可以大幅度变化的原子核形状，通过合理选取与三参数有关的核子单粒子势，用基矢展开法求解单粒子运动Ｓｈｒｏｄｉｎｇｅｒ方程，用矩阵对角化方法求出了与核形状有关的核子单粒子能级。分析表明，本文计算出的单粒子能级是合理可信的，可用于计算大形变核之形变位能的壳修正和对修正。此工作在裂变动力学模拟计算中是不可缺少的。In this paper , the three-parameter {c,h ,a} rotating body model is used to describe the shape of nuclei which can be changed with great amptitude.By Choosing reasonably the shape-dependent single particle potential of nucleon, the Schrodinger equation of single particle motion is solved by means of basic vector expansion method. Using the method of diagonizing the matrix, We calculated the shape-dependent single particle energy levels of nucleon. By analyzing and comparing these calculated results with those obtained by other authors under the same condition, these calculated results are confirmed to be reliable and rational , which can be used to calculate the shell correction and pair correction of deformation potential of great-deformed nuclei.
