Energy Levels and Spectral Lines for n=3 to n=3 Transitions in Mg-Like Tungsten Ions

Abstract

Energies and transitions for allowed (E1) and forbidden (E2, M1, and M2) lines for low-lying congurations in magnesium-like tungsten (W 62+ ) are studied using the multiconguration DiracHartreeFock approach. It is shown that the correlations within the n = 3 complex, quantum electrodynamic and Breit eects are very important for the calculation of ne structure energies. The present results are compared to and agree very well with other theoretical energies, wavelengths, transition probabilities and line strengths previously published for a few lines, and are generally found to be more reliable than previous theoretical predictions. The data for E2, M1, and M2 for transitions between the levels are presented as supplemental material. Results are also compared with other theory, when available.
