Abstract

The Ar L 2,3 -MM Auger spectrum induced by impact of 2.0 keV electrons was measured with high resolution (68 ± 4 meV) in the 15-90 ° angular region. Relative yields, level widths and transition energies have been determined for the diagram Auger lines originating from the 2 P 1/2 and 2 P3/2 initial vacancy states. The data are compared with those of earlier experimental studies and theoretical calculations, including multiconfiguration Hartree-Fock calculations performed in this work. The isotropy of the studied lines has been confirmed. The measured relative intensities of the fine-structure components of the L 23 -MM ( 3 P0, 1, 2) Auger triplets have been found different from those obtained in theoretical calculations and earlier experiments.
