Theoretical Study of Electron Exchange under Grazing Scattering on Thin Metal Films

Electron exchange during grazing scattering of hydrogen ions on thin metal films is considered. The main characteristic being studied is the yield fraction, that is, the probability of the formation of a certain charge state of a scattered particle (in the case under consideration, H^–) as a function of the velocity component parallel to the surface of the sample. Based on an analysis of the electron distribution in the space of wave vectors and the application of the generally accepted model of displacement of Fermi spheres, it was shown that the dependence of the probability of the formation of a negative hydrogen ion on the parallel velocity component should decrease monotonically.
