Abstract

In this paper, we have performed accurate, high-lying theoretical calculations of the resonance energies and quantum defects of several series of autoionizing Rydberg resonances of the Ne2+ ion of interest to astrophysics and plasma physics via the modified atomic orbital theory (MAOT) method. The calculated resonance energies are in very good agreement with existing experimental data from the Advanced Light Source (ALS), and the discrepancies between theoretical calculation values and experimental data are minimal. In addition, this study calculates and compares all the uncertain energy positions in the ALS measurements. This comparison provides greater confidence in the ALS data and the new extrapolated results for astrophysical applications.
