Abstract
We report on the scattering of 3 keV He, Ne, Ar, Kr, Xe atoms and singly ch arged ions from a Cu(111) surface under grazing angles of incidence. Polar angular distributions of scattered neutral projectiles show a well-defined peaked structure in the direction of specular reflection with a small FWHM of typically 0.5 degrees at an incidence angle of 1 degrees. The measured d istributions are compared with elastic scattering computer simulations and previous studies by Harder et al. [Surf. Sci. 289 (1993) 214]. (C) 2001 Els evier Science B.V.
