摘 要:研究了原子核平均场中本征能量的求 解.当不存在任何几何对称性时,能量矩阵由2N×2N个复数矩阵元组成(N为基矢的大小);如果空间存在1个反射对称平面,该2N×2N复矩阵可约化为1对互为共轭N×N复矩阵或1个2N×2N实矩阵;如果存在2个互相正交对称平面,则可约化为2个N×N实矩阵.
Abstract: The solutions to the eigen energy problem in nuclear mean field are investigated. If there is no geometry symmetries in the coordinate space, the energy matrix is composed of 2 N×2N complex matrix elements( N is the size of the basis employed). If there exists one reflection symmetrical plane, this 2N×2N complex matrix can be reduced to a pair of conjugate N×N complex matrices or one 2N×2N real matrix. And if there are two perpendicular reflection planes, it can be further reduced to two N×N real matrices.
