We have calculated the differential cross sections and polarization observables for elastic and inelastic scattering of intermediate-energy protons on "C and I6O nuclei on the basis of the multiple diffraction scattering theory with the nucleon density and transition density obtained from the w-cluster model with dispersion and from model-free analysis. We have shown that there is a qualitative difference between the elastic scattering spin-rotation functions calculated by the =-cluster model with dispersion and by the independent-nucleon model.

The differential cross-sections and polarization observables of 800 MeV proton and 1.37 GeV α-particle elastic scattering on 20 Ne nuclei are calculated on the basis of multiple diffraction scattering theory and α-cluster model with dispersion. It is shown that α-cluster structure is strongly manifested in 20 Ne nuclei and the assumption about that allows us to agree with the calculated and measured observables in the elastic 800 MeV proton scattering on these nuclei.

The multiple diffraction scattering theory and the α-cluster model with dispersion have been applied for calculations of the observables for the elastic scattering of intermediate energy protons by 20 Ne and 24 Mg nuclei. The target nuclei are considered as composed of the core (16 O nucleus) and additional α-clusters (one α-cluster for 20 Ne nucleus and a dumb-bell α-cluster configuration for 24 Mg nucleus). Taking into account the α-cluster configuration of the core, it was supposed that the additional α-cluster or center of mass of the dumb-bell are arranged with the most probability inside or outside of the core. The calculated observables for the elastic p–20 Ne and p–24 Mg scattering are in agreement with the existing experimental data. The influence of the deformed core contribution on the behavior of the calculated observables also is tested.
