The angular distribution of fast charged particles scattered on a perfect crystal is studied. By introducing the many‐particle correlation functions the velocity distribution function convenient for numerical analysis is obtained. It is shown that this distribution depends essentially on correlations between the thermal atomic displacements of a lattice. A two‐particle model is considered as a particular case, which results are compared with experimental data. It is evident that even in this simplest case the axial symmetry of the scattering yield is disturbed. This is determined by the difference of the various correlation tensor's components as found.
