Abstract
The fully relativistic transition probabilities in atomic X-ray emission are calculated for a wide range of selected elements of the periodic table, fromZ=21 toZ=93. The treatment includes the effect of the retardation of the radiation field. The atomic model used is the self-consistent relativistic Hartree-Fock, with the Slater approximation for the exchange term. The formulas for EL and ML multipole transition rates are derived, and transition rates are calculated for all transitions to theK-shell,L-subshells, andM-subshells. The contributions of all multipoles, as determined by the angular momentum and parity selection rules, are included in the present work. The calculated values of (Kα2/Kα1), (Kβ1/Kα1), (Kβ3/Kβ1) and (Kβ2Kβ1) transition rates are in good agreement with the available experimental data. Rates for the forbidden (M1) 2s1/2→1s1/2 transitions are also presented.
