摘　　要：在最弱受约束电子势模型理论下,研究了外来微扰能级对里德堡能级系列的影响,给出了确定外来微扰能级位置的方法.依此计算了钡原子6snp(n≥15)3P1和6snd(n≥9)3D3两个里德堡能级系列的量子数亏损和能级.计算结果和实验值的绝对误差在1 cm-1以内,达到了较高的精度.The effect of foreign perturbing levels on a Rydberg energy levels series is investigated with the weakest bound electron potential model （WBEPM） theory. A method of determining the energy of foreign perturbing levels is set out. By means of the method＇, the energy levels and quantum defects of the perturbed Rydberg series 6snp （ n≥15）^3p1 and 6snd （ n≥9）^3D3 are calculated for barium atom. The accuracy of most of our results that have been reached is less than 1 cm^- 1. It is very good among all the present theoretical methods.
