Angular distributions of the 6Li(18O, 17O)7Li reaction were measured at Elab(18O) = 114 MeV for ground and excited states of exit nuclei. The data were analyzed within the coupled-reaction-channels method (CRC). The 6Li + 18O elastic and inelastic scattering channels as well as the simplest one- and two-step reactions were includ-ed in the coupled-reaction-channels scheme. In CRC calculations, the 6Li + 18O potential with parameters de-duced from the elastic scattering data, was used for the entrance reaction channel. The spectroscopic amplitudes of nucleons and clusters were calculated within the translational-invariant shell model. The 7Li + 17O potential parameters were deduced by fitting 6Li(18O, 17O)7Li reaction data. Isotopic differences of the 7Li + 17O, 7Li + 18O and 7Li + 16O potential, as well as the reaction mechanisms are studied.
