We present a model for electron emission from Al surfaces by Auger neutralization of 130–430 eV Ar+ ions, thatincludes the singular response of the metal conduction band to the abrupt change of the surface potential caused byelectron capture by the incident ion. This effect, previously identified in X-ray studies, produces a broadening that playsa significant role in reproducing the higher energy part of the experimental electron kinetic energy distributions.

Abstract
We present a model for electron emission from Al surfaces by Auger neutralization of 130–430 eV Ar+ ions, thatincludes the singular response of the metal conduction band to the abrupt change of the surface potential caused byelectron capture by the incident ion. This effect, previously identified in X-ray studies, produces a broadening that playsa significant role in reproducing the higher energy part of the experimental electron kinetic energy distributions.File in questo prodotto:
