【摘要】 利用Racah代数和反对称化子技巧,对复杂组态下单电子和双电子算符的非相对论性矩阵元进行了讨论。在我们的表达式中,径向积分系数只含6j符号(或第一类3nj符号)和单电子亲态比系数,且仅需对亲态求和。因此按照这些表达式,可以相当容易地计算出复杂原子的能级。更多还原

【Abstract】 The npn-relativistic matrix elements of one- and two-electron operators for complex configuration are discussed by using the Racah algebra and antisymmetrizer techniques. In our final expressions, the coefficients of radial integral consist of 6-j symbols (or 3n-j symbols of the first kind) and one-electron coefficients of fractional parentage with parent summation only. As a result, the complex atomic energy levels can be evaluated according to these expressions more easily.更多还原
