Abstract
Based on the solution of Boltzmann kinetic equation, an approximate expression is obtained for the distribution function describing a nonstationary energy distribution of a cascade of moving atoms. The development of the cascade is considered in materials consisting of identical atoms with allowance for the bond energy of atoms in the lattice (εd). It is assumed that the scattering of moving atoms is elastic and spherically symmetric in the center-of-mass system and the interaction cross section is inversely proportional to the velocity. The effect of the bond energy of atoms on the distribution function and related quantities is analyzed based on the obtained solution. In the limiting case of εd = 0, the approximate solution is in good agreement with the exact solution of the corresponding problem.
