Abstract

We present the results of high-resolution measurements of the low-energy part of the Auger electron spectrum generated by photoexcitation of the 1s -13p resonance in Ne. The spectrum was measured in the energy range of 10-33 eV where mainly the electrons from the second-step Auger transitions of the cascades 1s-13p → 2s2p5np → 2s2 2p4 and 1s-13p → 2s02p 6np → 2s2p5 (n -3, 4) are detected. High resolution allows us to study the multiplet structure of the transitions and to determine the widths of the intermediate states of the Ne+ ion. Anisotropy of the angular distribution of Auger electrons is determined for all of the lines observed. The results are in reasonably good agreement with MCDF calculations.
