The chemi-ionization processes in slow-atom–Rydberg-atom collisions are considered in this paper. A version of the semiclassical method of rate coefficient calculation that is free of the presumptions which significantly limited its applicability previously is presented. The method is applied to the cases of Li*(n)+Li and Na*(n)+Na collisions for the principal quantum numbers 5≤n≤25 and temperatures 600≤T≤1200  K . The results of calculation of the rate coefficients of the corresponding chemi-ionization processes are compared to the existing experimental data from the literature.
