Résumé : Experimental results are presented concerning crystallographic effects on the Auger electron emission from (110) aluminum single crystal surfaces irradiated with argon ions. A comparison is made with previous data obtained with a polycrystalline target. The dependences of absolute L//2//3MM and L//2//3VV Auger yields are measured as functions of both the incident beam energy (7-70 kev) and direction (0 degree -60 degree from the surface normal). The data are discussed by comparison with computer simulation using the MARLOWE program. The calculation procedure allows us to distinguish between the emission from the bulk, including the effect of the surface neutralization, and from sputtered excited atoms. The model takes into account the thermal vibrations which were found to be of no significant influence. The width dependence on the incidence angle and ionic energy is weak in the range investigated.
