Transition energies and relative intensities of the Ar L_2,3-MM diagram auger lines: a high-resolution study

摘要

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 ~2P_1/2 and ~2P_3/2 initial vacancy states. The data are compared with those of earlier experi- mental studies and theoretical calculations, including multiconfiguration hartee-Fock calculations performed in this work. The isotropy of the studied lines has been confirmed.
