Abstract
The scattering trajectory and stopping power for H+ ions at glancing angles of incidence on a solid surface have been investigated using the dielectric response theory and specular reflection model. When an ion moves near the solid surface, it will be subjected to the repulsive force of the surface atoms and the dynamical force yielded by the surface induced potential. A local-field correction dielectric function and a local frquency-dependent dielectric function with a damping factor have been adopted respectively in low and high velocity approximations. The energy loss is obtained and has been compared with the experiment results.
