Wavelengths, transition rates, weight oscillator strengths and line strengths for He-like to Ne-like cobalt ions

Abstract

The multi-configuration Dirac–Hartree–Fock (MCDHF) and Relativistic Configuration Interaction (RCI) methods have been used to calculate the wavelengths, transition rates, absorption oscillator strengths, and line strengths for the 2s-3p, 2p-3s, and 2p-3d electric dipole (E1) transitions in He-like to Ne-like cobalt ions. Breit interaction and quantum-electrodynamical (QED) contributions were estimated in extensive RCI calculations. The results are in good agreement with previous experimental and theoretical results. Our calculated wavelengths differ from wavelengths reported in other work mostly by less than 0.78%, with two exceptions, where our results differ by 1.63% and 1.91%, showing good overall confirmation of the accuracy of our results. Most importantly, we have predicted some theoretical data that, will be helpful in some plasma experiments.
