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

100%

Hao L., Kang X.

Energies and transitions for allowed (E1) and forbidden (E2, M1, and M2) lines for low-lying configurations in magnesium-like tungsten (W^{62+}) are studied using the multiconfiguration Dirac-Hartree-Fock approach. It is shown that the correlations within the n=3 complex, quantum electrodynamic and Breit effects are very important for the calculation of fine 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.

Energy levels, wavelengths, transition rates and line strengths are reported for the 2s^22p^3-2s2p^{4} transition array in Kr(XXX), Rb(XXXI) and Sr(XXXII). Wave functions were determined using the multiconfiguration Dirac-Fock method with account for valence and core-valence correlation effects. The present results are presented and compared with experimental data and with values from other calculations. The calculated values including core-valence correlation are in good agreement with other available theoretical and experimental values, and therefore can be used for the further astrophysical investigations.
