Energy levels, wavelengths, transition probabilities, and line strengths of Si-like Se ions

Abstract

The multi-configuration Dirac–Hartree–Fock (MCDHF) method and the active space approach have been employed to investigate the energy levels, wavelengths, transition probabilities, and line strengths of Si-like Se ions. The contributions of Breit interaction (BI) and quantum electrodynamic (QED) correction are taken into consideration. The wavelengths, transition probabilities, and line strengths of Si-like Se ions have also been calculated. Compared with other theoretical and experimental values of these parameters, our values are in good agreement with others, and the number of energy levels we considered is larger than that of any other theoretical calculations.
