摘要: 应用推广Schaefer和Harris的方法(即对于给定的电子组态,在Slater行列式基上构造算符L2+λS2的矩阵,通过对角化此矩阵求得LS耦合原子态的本征函数)开发一套Fortran程序,不仅可以求得某一对称下最简洁的的LS本征函数,而且能够求得任一电子组态(同科电子组态和非同科电子组态)的所有LS耦合原子态.作为例子,具体计算Np(Z=93)电子组态5f46d的LS耦合原子态和对应于6I光谱项的最简洁的LS本征函数.

关键词: 电子组态, Slater行列式, LS耦合原子态, 本征函数

Abstract: With Schaefer and Harris method, i.e., constructing LS eigenfunctions by diagonlization of L2+λS2, a FORTRAN code with two modes is developed to calculate the most concise LS eigenfunctions under certain symmetry and all LS coupling atomic states (both non-equivalent and equivalent electronic configurations) with given orbital occupancy. As an example, LS coupling atomic states and the simplest LS eigenfunctions for 6I symmetry of Np (Z=93) 5f46d electronic occupancy are calculated.

Key words: electronic configurations, slater derterninants, LS coupling of atomic states, eigenfuntions
