Ne K Auger cross sections from 1.5 MeV/amu H, O and F

Abstract

Ne K-shell Auger electron production cross sections, sigma A, have been measured for Ne bombarded by 1.5 MeV/amu H, O, and sigma A is found to increase with increasing projectile charge state which is a clear indication that the K-shell vacancy production cross section, sigma , is increasing with increasing projectile charge state since the fluorescence yield, omega , is increasing with increasing charge state and since sigma = sigma A/(1- omega ). The cross sections are compared to Coulomb ionization predictions.
