Abstract:

The fine structure of the energy spectra of Cs ions scattered by the 110, 001 and 112 faces of a tungsten single crystal is investigated under conditions of sufficiently high angular and energy resolution. Angular dependences of the energy corresponding to various peaks in the scattered ion spectrum of angle of incidence of the primary ions on the target surface for a given scattering angle are derived. The model of group interaction between an ion and four or three lattice atoms and the model of pair double or triple collisions are invoked for explaining the shifts of the bell-shaped curve peaks along the incidence angle scale for various scattering atomic directions.
