In the approach, the dynamical surface scattering LEED and exchange potentials are expressed in terms of the effective scattering potentials of a free atom. The SPLEED exchange scattering asymmetry during the reversal of the polarization direction of the incident electron beam are given in analytical form and the asymmetry effects are computed numerically. The temperature dependence of the surface polarization effect for nickel surfaces is presented graphically. The obtained results correspond to those of experiments and literature.

Transition radiation emitted when a nonrelativistic particle (β=0.2-0.5) enters a surface irregularity shaped as a rectangular step and a rectangular groove and having the dielectric constant ε=1.4-3.8 has been investigated. The angular distribution of the radiation intensity as well as its dependence on the height of the irregularities, the width of the groove and the distance between the irregularity edge and the entry point of the particle have been calculated on the basis of the theory of Bagiyan and Ter-Mikaelyan.
