摘要
We study the angular distributions of multicharged noble gas ions after scattering from a clean and a cesiated Al(111)-surface under a grazing angle of incidence. The data show pronounced effects of the image charge attraction on the incident trajectory which allow us to deduce the energy gained by the projectile during the approach towards the surface. We present a detailed discussion of our experimental method and compare the results with an ''over-barrier model'' describing the neutralization of multicharged ions in front of a metal surface.
