Abstract: In this paper, the results of theoretical calculation of five Rydberg series energy levels 5d_{3/2} \to np_{1/2} (n=6--20), 5d_{3/2} \to nf_{5/2} (n=5--20), 5d_{5/2} \to np_{3/2} (n=6--20), 5d_{5/2} \to nf_{7/2} (n=5-20) and 5d_{5/2} \to nf_{5/2} (n=5-20) for Pb III ions are presented using the weakest bound electron potential model (WBEPM) theory, considering foreign level perturbation corrections. The theoretically calculated results agree very well with present known experimental data, and some energy levels without experimental values are predicted.
