Abstract
The energy loss of slow ions scattered off an Al(111) surface is explained using a theoretical description based on scattering theory. The explicit inclusion of gradient corrections to account for a nonuniform electron density at the surface provides good agreement with the measured data over a wide range of distances (electron densities) for different ions with atomic number
