6 Li( 18 O, 17 O) 7 Li reaction and comparison of 6, 7 Li+ 16, 17, 18 O potentials

Angular distributions of the 6Li(18O, 17O)7Li reaction were measured at Elab(O18)=114MeV for ground and excited states of the exit channel nuclei for the first time. The data were analyzed within the coupled-reaction-channels method (CRC). The 6Li+18O elastic and inelastic scattering channels as well as simplest one- and two-step reactions were included in the coupled-reaction-channels scheme. The 7Li+17O potential was deduced by fitting CRC calculations to the reaction data. The spectroscopic amplitudes for single nucleon and nuclear cluster configurations were calculated within the translationally invariant shell model. Isotopic differences of the 7Li+16, 17, 18O and 7, 8Li+17O potentials and the reaction mechanisms were studied.
