STUDIES OF EJECTED-ELECTRON SPECTRA ARISING FROM O6-HE, NE, AR AND N5+-HE, NE, AR COLLISIONS()

Electron energy spectra arising from collisions between He-like ions ( O6+ and N5+) and rare gas atoms (He,Ne and Ar) were measured using zer o-degree Auger electron spectroscopy with high energy resolution. The electrons were ejected from doubly excited Be-like ions produced by do uble electron capture from the targets. Triplet states in the doubly e xcited systems were predominantly produced in O6+-Ne and N5+-Ar collis ions.
