Calculation of Transition Probabilities Using Multiconfiguration Dirac-Fock Method

Abstract

The performance of the multiconfiguraton Dirac-Fock (MCDF) method in calculating transition probabilities of atoms is reviewed. In general, the MCDF wave functions will lead to transition probabilities accurate to ~ 10% or better for strong, electric-dipole allowed transitions for small atoms. However, it is more difficult to get reliable transition probabilities for weak transitions. Also, some MCDF wave functions for a specific J quantum number may not reduce to the appropriate nonrelativistic limit for the L and S quantum numbers. Transition probabilities calculated from such MCDF wave functions for nonrelativistically forbidden transitions may become unreliable. Remedies for such cases are discussed.
