Electron spectroscopic studies of the neutralization of slow multicharged ions during interactions with a metal surface
Recent experimental results of electron spectroscopic studies of the neutralization and relaxation of slow multicharged ions interacting with metal surfaces are summarized. Discussed are measurements of projectile K-Auger electron emission during interactions of N{sup 6+} ions with clean and cesiated Au, as well as clean Cu single crystal targets. While the dominant component in the measured K-Auger spectra is shown to be due to sub-surface electron emission, at incident perpendicular velocities below about 10{sup {minus}2} au, small features become evident in the measured K-Auger spectra that are consistent with above surface projectile electron emission. Experimental results are compared with results of modelling studies of above- and sub-surface electron emission. Also presented are measurements of low energy electron emission during multicharged ion-surface interactions, together with a discussion and analysis of the various contributing low energy emission mechanisms.
