  ABSTRACT: We report in this paper energy positions of the 2P°_2s22p2(1D)nd 2P, 2P°_2s22p2(1D)nd 2S, 2P°_2s22p2(1D)ns 2D, 2P°_2s22p2(1S)nd 2D, and 2P°_2s22p3(3P)np 2D Rydberg series in the photoionization spectra originating from 2P° metastable state of O+ ions. Calculations are performed up to n = 30 using the Modified Orbital Atomic Theory (MAOT). The present results are compared to the experimental data of Aguilar which are the only available values. The accurate data presented in this work may be a useful guideline for future experimental and other theoretical studies.
