Relativistic Lshell Auger and CosterKronig rates and fluorescence yields
Abstract
Relativistic calculations of radiationless transition rates to L subshell vacancy states in selected atoms with Z in the 7096 range have been performed. The Auger and CosterKronig transition probabilities are calculated from perturbation theory, assuming frozen orbitals, in the DiracHartreeSlater approach. Transition rates, fluorescence yields, and CosterKronig yields are compared with nonrelativistic theoretical results and with experiment. Relativity is found to affect the L subshell Auger widths by (1025)% and individual transition rates to certain jj configurations by as much as 40% at Z = 80. The widths of L sub i vacancy states and the L sub 2 CosterKronig yields f33 from these relativistic calculations agree much better with experiment than earlier nonrelativistic theoretical values.
