High-Resolution ArKAuger Spectrum Produced in 4-MeVH+on Argon Collisions

Abstract
Ar K Auger electrons produced by 4-MeV proton impact on argon are measured with 2-eV (full width at half-maximum) spectroscopic resolution. A previously observed Ar K Auger spectrum resulting from 6-keV electron bombardment is compared to the proton-induced spectrum.
