Abstract. An analytical method for calculation of secondary nucleons double-different?ial distributions based on the solution of kinetic equations in the case of small angular approximation is developed. The comparison of the obtained results for the double-differential cross-sections with experimental data for initial protons of energy 200 MeV is carried out. The importance of the quantum effects for the correct assessment of quasi-free component of tile nucleon-nucleus interaction cross-section is demonstrated in the case of intermediate-range energy of the incoming nucleon.
