Abstract

Pr II is first ion of atomic Praseodymium (Pr) (rare Earth element with Z = 59). In this study, we investigated electronic configurations 4f^3 6p& 4f^3 6s of singly ionized Praseodymium and studied its fine levels structure. We used Russell Saunders technique to calculate spectral terms, total angular momentum. The possiblespectroscopic terms for(i)4f^3 6p(ii) 4f^3 6s configurations are 98 and 34, respectively. The total number of J valuescorresponding to these configurations is 242 and 82, respectively. In addition, we investigated configuration 4f^2 5d^2 and also found term energies arising from coulomb interaction. The total number of spectroscopic LS terms for 4f^2 5d^2 are 187, Coulomb energies have also been calculated for these spectroscopic terms. The information presented in this paper could be further used to find other spectroscopic characteristics of the configurations.
