A semimicroscopic approach to the description of the interaction of low-energy nucleons with nuclei is presented. The optical potentials and form factors of inelastic transitions are obtained in a closed form on the basis of effective nucleon-nucleon forces, which depend on the density of the matter distribution in the nucleus, and allowance for the Pauli principle in the density-matrix formalism. The influence of exchange effects on the properties of the nucleon--nucleus interaction is analyzed. A semimicroscopic coupled-channel method is formulated and used to analyze experimental data on the elastic and inelastic scattering of protons by nuclei. The connection between the deformation parameters of the nucleon potential and the parameters of the isoscalar and isovector deformation of the nuclei is investigated in the isospin formalism. The contribution of exchange effects to the energy dependence of the isobaric-spin potential is established.
