Abstract
We investigate the influence the surface description when channeled protons collide grazingly with surfaces in the energy range. The projectile is considered to move taking into account the (static and dynamic) potentials with all the ions of the grid. In this model the surface reveals not as an impenetrable isotropic plane but as a complicated percolator strongly dependent on the crystallographic indices, and on the initial conditions.
