Accurate multiconfiguration Dirac-Hartree-Fock calculations of transition probabilities for magnesium-like ions
چکیده انگلیسی


- Multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction calculations were used.
- The valence-valence and core-valence correlations are considered.
- Energy levels and transitions probabilities are calculated for 35 levels of magnesium-like ions.
- Detail QED and total energy for four configurations were presented.

Results from multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) calculations are presented for the n=3 to n′=3 transitions in the Mg isoelectronic sequence. The calculated values for the lowest 35 levels including core-valence correlation are found to be similar and to compare very well with other theoretical and experimental values. The Breit interaction and leading quantum electrodynamic effects are included as perturbations. The calculations can provide useful data for the experimental study of determining the fine structure levels in future work.
