Résumé : Experiments and computer simulation of Al L23 absolute Auger yields from single-crystal and polycrystal aluminium targets bombarded by Ar+ ions were peformed. From experimental Al Auger Spectra, band-like and atomic-like structures labelled L23VV and L23MM respectively can be distinguished. The dependences of these experimental Auger yields on the incidence angle and ionic energy were studied. Comparison with calculated variation laws of Auger yields from 2p excited Al atoms decaying inside the crystal (bulk emission) and from excited sputtered atoms was carried out. The model was set up on the basis of the atomic collision cascade as generated by the MARLOWE code. Reasonable agreement between experimental and calculated results was obtained in taking into account the Auger neutralization process involving electron exchange between metal and sputtered atoms.
