Abstract
A computer simulation method has been used to study small angle correl ated scattering of low energy ions by a single crystal surface with su bmonolayer adsorption coverages. It has been shown that a rainbow effe ct and a chain effect at multiple scattering on adsorbate and substrat e atoms and inverse ratio of masses of colliding particles lead to the appearance of additional peaks in angular and energy distributions. A n analysis of these peaks and of the dynamics of their change upon ads orption as compared with experiment makes it possible to control the i nitial stages of adsorption and to identify adsorption structures by m eans of small angle ion scattering spectroscopy (ISS).
