Formation of the hollow 1so1S state of Ne2+ by electron impact: Observation by means of an Auger hypersatellite
Abstract
A weak Auger transition at 870.5+/-0.3 eV has been observed in neon for electron impact energies above the double K-shell ionization threshold (1863 eV). The Auger energies and transition rates identify the transition as the strongest Auger hypersatellite decay channel, KK-KL23L223D, of the hollow 1so 1S state of Ne2+. The production cross section of the 1so 1S state by electron impact was determined for energies up to three times the threshold ionization energy and found to agree reasonably with the binary encounter calculations.
