[en] On the basis of the folding model formalism a calculation scheme is developed which permits to calculate in a simple way the contribution of exchange and many-particle correlations into interaction of low energy nucleons with deformed nuclei. Differential cross sections of elastic and inelastic excitation 2¹⁺ state scattering of 23.95 and 17.5 MeV protons on a ₂₆Mg nucleus target are calculated. Satisfactory description of experimental angular distributions is obtained. The role of exchange and many-particle correlations in forming cross sections of scattering to large angles is studied. The contribution of the direct mechanism into 9.1 MeV proton scattering on ₂₆Mg is calculated. The relation between quadrupole deformation of a nucleus and potential and mechanisns of inelastic proton scattering is analysed
