On the nuclear interaction potential in the heavy ion reactions

The interaction potential of heavy ions 4He, 6Li, 12C and 16O is constructed in the folding model. The density of nuclear matter distribution for these nuclei is calculated in the framework of the hyperspherical function method. For the calculation of the folding potential the Skyrme two-body nucleon-nucleon forces were employed. The influence of several effects on the results of calculation is studied. Density dependence of the nucleon-nucleon interaction, dependence of the folding potential on the number of particles, the potential symmetry in the interaction of identical and different particles and the possibility of observing the monopole-resonance in the ion inelastic scattering are investigated. The investigations showed that the higher is the nuclear excitation energy the wider and shallower is the form of a potential. Non-diagonal matrix elements are not negligible. Nevertheless, in order to estimate the degree of the monopole giant resonance manifestation in the heavy ion collisions, it is necessary to carry out the direct calculation of inelastic collision cross-section for two heavy particles including the calculation over this channel into the scheme
