energy dependence of the 13c + 16o scattering and quasi-molecular absorptian potential

Experimental data of the 13С + 16O elastic scattering at the energies Еc.m.. = 6.28 - 59.17 MeV were analyzed within the optical model and coupled-reaction-channels method. The energy dependence for the 13С + 16O potential of the Woods - Saxon type with volume and the surface absorption was studied. It was found that the absorption potential has quasi-molecular form with narrow maximum in the surface region, which can be caused by a resonance of the 29Si = 13С + 16O two-nuclear system. The contributions of simple transfers in the 13С + 16O elastic scattering were obtained.
