Abstract: Experimental data of the ¹³С + ¹⁶O elastic scattering at the energies Е_c.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.

Keywords: elastic heavy-ion scattering, transfer reactions, optical model, coupled-reaction-channels method, optical potentials, spectroscopic amplitudes of nucleons and clusters.
