Abstract

Considering the perturbation, the results of theoretical calculation of five Rydberg series energy levels 6s^2ns^2S_1/2(n=7-20),6s^2nd^2D_3/2(n=6-20),6s^2nd^2D_5/2(n=6-20),6s^2np^2P^(0)_(1/2)(n=7-20), and 6s^2np^2P^(0)_(3/2)(n=7-20) for Tl I are presented using the weakest bound electron potential model (WBEPM) theory. Furthermore, the radiative lifetimes of this five series are also calculated. The calculated values of energy levels and lifetimes are in good agreement with the experimental results.
