Abstract
The absolute Auger rates, relative intensities and the angular anisotropy coefficients of Auger electrons have been calculated for the KLL Auger spectra of laser-excited sodium atoms. Where in closed-shell atoms the KLL Auger lines have to be isotropic this is no longer valid for certain Auger transitions in open-shell systems. To study the KLL Auger spectra of excited sodium atoms we calculated the Auger matrix elements within the multiconfigurational Dirac - Fock model using the intermediate coupling scheme for representing the atomic states. The intensities and angular distribution parameters are discussed together with theoretical predictions in the LS coupling and compared to results obtained for the sodium ground-state KLL Auger transitions. We also discuss the influence of overlapping initial fine-structure states on the Auger dynamics. Large anisotropy coefficients are predicted, even for the case of a non-resolved initial- and final-state fine structure. .
