Abstract

In this paper, we reported the energy positions, quantum defect and effective nuclear charge the triplet  and singlet  of the Rydberg series of Se3+ ions. Calculations are performed using the semi-empirical Modified Atomic Orbital theory (MAOT) from n = 6 to n = 45. The present results are compared to the experimental data of Esteves et al. and also to the theoretical calculations of Sakho et al. The accurate data presented in this work may be a useful guideline for future experimental and other theoretical studies.
