Abstract: Angular distributions of the ¹²C + ¹⁸O elastic and inelastic scattering were measured at the energy E_lab(¹⁸O) = 105 MeV (E_c.m. = 42 MeV). These data and data known from the literature at the energies E_c.m. = 12.9 - 56 МеV were analysed within the optical model and coupled-reaction-channels method. The sets of the Woods-Saxon (¹²С + ¹⁸O)-potential parameters were deduced and their energy dependence was studied. It was found the isotopic differences in the (¹²С + ¹⁶O)- and (¹²С + ¹⁸O)-potentials parameters and in their surface forms. The mechanisms of elastic and inelastic (¹²С + ¹⁸O)-scattering and role of transfer reactions were studied.

Keywords: nuclear reactions, optical model, coupled-reaction-channels method, folding-model, spectroscopic amplitudes, optical potentials, reaction mechanisms.
