Influence of the wave reconstruction on the energy loss of charged particles in thin films

Abstract

The rearrangement of the state of the particle incident from a vacuum on a surface of a solid causes changes in the cross-sections of its elastic and inelastic collisions with atoms. The specific energy loss changes as the particle penetrates into the medium, experiencing a gradual decrease at sufficiently large velocities (in the electron gas at ν> νF.), mostly significant in the neighbourhood of the point of maximal stopping power of the medium. The theory is found to be in satisfactory agreement with the experimental data.
