The possibility of separating the interactions that occur between elementary particles and nuclei into coherent and incoherent processes and the validity of the single-particle approximation in the analysis of the behavior of these particles in a nucleus allow a constructive solution of the problem of describing the incoherent processes of interaction of particles with nuclei with the use of dispersion relations and the diagrammatic technique. The thus arising equations for the single-particle Green functions describing the behavior of the single-particle component in the nucleus can be solved in the quasiclassical approximation. This circumstance allows us to formulate an approach to the description of nuclear reactions that employs the methods of kinetic theory. It is shown that this approach allows the analysis of the behavior of a fast particle in a nuclear reaction. A comparison of the results obtained with the experimental data leads to the conviction that the present approach allows the description of both the experimental data on the inelastic interaction of pions with a nucleus and the processes of pion and nucleon production on nuclei by intermediate energy protons.
