Description
The interaction between helium metastable atoms and a solid surface has been experimentally studied in order to obtain a better understanding of the de-excitation mechanisms. The stage of ionization is indicated by the He+ ions by direct measurement. Thus the validity of one of the mechanisms theoretically discussed by Hagstrum is corroborated
Abstract (French)
L'interaction d'atomes métastables d'hélium d'énergie cinétique thermique avec la surface de solides est étudiée expérimentalement afin de mieux comprendre les mécanismes de désexcitation. L'étape de l'ionisation est mise en évidence par la mesure directe des ions He+. On confirme ainsi la validité de l'un des mécanismes discutés par Hagstrum théoriquement.Additional details
