| Abstract: | 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 and are calculated for barium atom. The accuracy of most of our results that have been reached is less than 1cm-1. It is very good among all the present theoretical methods |
