Abstract

Synopsis: Double differential electron emission distributions produced by grazing impact of fast dressed ions on a Cu(111) surface are investigated focusing on the effects of the electronic band structure. The process is described within the Band-Structure-Based (BSB) approximation, which is a perturbative method that incorporates information of the electronic band structure of the solid. Differences in the behavior of the emission spectra for He + q, Li + q, Be + q and C + q projectiles with different charge states q are explained by the combined effect of the projectile trajectory and the projectile charge distribution.
