Résumé
La statistique des électrons émis par impact d'ions mono ou multichargés sur des surfaces métalliques est étudiée afin de différencier les contributions de l'émission potentielle. En particulier, nous discutons du nombre d'électrons émis dans le cas d'impact d'ions Ar^q+ (q = 1 - 4) sur de l'or polycristallin.

Abstract
The statistics of electrons emitted due to impact of singly and multiply charged ions on metal surfaces is investigated in view of different contributions from potential emission. As an example we discuss the number of electrons emitted for impact of Ar^q+ (q = 1 - 4) on polycrystalline gold.
