Mikhailyuk V. Theory of interaction of intermediate energy particles with light nuclei in the cluster model.

The thesis is devoted to elaborating the theoretical approach for the investigation of density regularities in light cluster nuclei, and for the description of wide range of phenomena observed at the interaction of particles and light intermediate energy nuclei with light nuclei. The alpha-cluster model with dispersion for even (20Ne) and odd (13С, 13N, 9Ве and 6Не) nuclei has been proposed. The many- and one-particle densities for these nuclei have been obtained. The calculated densities are compared with the existing experimental data. The model proposed allows us to describe the existing experimental data on differential cross-sections and polarization observables for the elastic and inelastic scattering of particles on these nuclei. The diffraction model has been developed to describe the scattering of complex nuclei in which number of clusters is equal or greater than two. In this approach both the structure of the projectile and the structure of the target nucleus are taken into account. On the basis of this model the existing experimental data for the elastic scattering of intermediate energy light nuclei by light alpha-cluster nuclei have been described.
