Energy loss and charge fractions of multicharged chlorine ions after grazing scattering from an Al(111) surface

Chlorine ions with charges up to 11 are scattered with energies ranging from 50 to 600 keV from a clean and flat Al(111) surface under a grazing angle of incidence. We have investigated energy loss and charge fractions of scattered projectiles. We find a weak dependence of the energy loss on the projectile charge, whereas the higher charge fractions of the scattered bean show pronounced effects on the charge of incident ions. (orig.)
