Electron emission by 130-430-eV Ar+ ion impact on polycrystalline Al surfaces is studied extending the theory of Auger neutralization to include the singular response of the metal conduction band to the sudden change of charge in the incoming hole state, following its neutralization. The effect is manifested in the high-energy tail of the electron energy distributions, where the theory accounts very well with experiments.

Abstract
Electron emission by 130-430-eV Ar+ ion impact on polycrystalline Al surfaces is studied extending the theory of Auger neutralization to include the singular response of the metal conduction band to the sudden change of charge in the incoming hole state, following its neutralization. The effect is manifested in the high-energy tail of the electron energy distributions, where the theory accounts very well with experiments.File in questo prodotto:
