- Abstract
Observables of the elastic and inelastic scattering of 800- and 250-MeV protons on Ne and Mg nuclei were calculated on the basis of the theory of multiple diffractive scattering and the dispersive α-cluster model. The Ne and Mg nuclei were assumed to consist of a core (O nucleus) and additional alpha-particle clusters, which could be situated with the highest probability both in the vicinity of the center of mass of the core and outside the core. The multiparticle densities of these nuclei and single-particle nucleon-distribution densities as obtained from the dispersive α-cluster model were used in the calculations. The differential cross sections and polarizations for elastic and inelastic pNe and pMg scattering at the energy of 800 MeV are in better agreement with experimental data than the analogous calculations at the energy of 250 MeV. The spin-rotation functions calculated in the singleparticle approximation for elastic pNe and pMg scattering at these two energy values differ qualitatively from their counterparts calculated on the basis of the dispersive α-cluster model.
