The angular distributions of the 7Li(18O, 17N)8Ве reactions have been measured firstly for ground and excited states of 8Be and 17N nuclei at the energy Elab.(18O) = 114 MeV. The experimental data have been analyzed within the coupled-reaction-channels (CRC) method for one- and two- step transfers of nucleons and clusters. The mechanism of given reaction was studied. Using for the entrance channel optical 7Li + 18O-potential deduced from the elastic 7Li + 18O-scattering and shell-model spectroscopic amplitudes calculated within the translation-invariant shell model (TISM), the parameters of the optical Wood-Saxon 8Ве + 17N-potential were obtained by fitting the experimental data. It was found that proton transfer dominates in the reaction. The 8Ве + 17N potential have been compared with the potentials for 8Ве interactions with 9Be, 13C, 15N.
16N + 9BE OPTICAL POTENTIAL FROM 7LI(18O, 16N)9BE REACTION ANALYSES
New experimental data of the angular distributions of the 7Li(18O, 16N)9Ве reaction were measured simultaneously with the 7Li + 18O scattering at the energy Elab(18O) = 114 MeV for ground and excited states of 9Be and 16N nuclei. The reaction data were analyzed within the coupled-reaction-channels (CRC) method for one- and two-step transfers. In the CRC-calculations, the 7Li + 18O potential deduced by fitting elastic scattering data was used. The needed spectroscopic amplitudes were calculated within the translation-invariant shell-model (TISM). The 9Ве + 16N potential parameters were deduced by fitting the reaction data. It was found that the deuteron transfer dominates in this reaction. The 9Ве + 16N potential are compared with that of 9Ве + 16О and 9Ве + 14N scattering.
