Abstract: The angular distributions of the ⁷Li(¹⁸O, ¹⁷O)⁸Li reaction were measured for the transitions to the ground and excited states of ⁸Li and ¹⁷O at the energy E_lab(¹⁸O) = 114 MeV. The data were analyzed with coupled-reaction-channels method for one- and two-step transfers of nucleons and clusters. In the analysis, the ⁷Li + ¹⁸O potential deduced in the analysis of the elastic ⁷Li + ¹⁸O-scattering data as well as shell-model spectroscopic amplitudes of transferred nucleons and clusters were used. The reaction mechanism was studied. The parameters of the ⁸Li + ¹⁷О potential were deduced and were compared with these of the ⁷Li + ¹⁸O potential. The ⁸Li + ¹⁷О folding-potential was calculated and compared with the deduced in the reaction data analysis.

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