Evidence of the effect of strong stripping channels on the dynamics of the Li8+Ni58 reaction

The ${}^8\mathrm{Li}+{}^{58}\mathrm{Ni}$ collision is investigated at 23.9, 26.1, 28.7, and 30 MeV bombarding energies. Quasielastic angular distributions and the singles ${}^7\mathrm{Li}$ angular and energy distributions are presented. Coupled-reaction channels (CRC) calculations, which include the coupling of the elastic channel to ${}^{59}\mathrm{Ni}={}^{58}\mathrm{Ni}+n$ states above and below the neutron threshold, provide a simultaneous description of the quasielastic and transfer distributions and evidence the strong effect of the one-neutron transfer/breakup channels on the quasielastic scattering. The ${}^7\mathrm{Li}$ angular and energy distributions have been also successfully analyzed combining the continuum discretized coupled channels (CDCC) method, for the elastic breakup, and the IAV model of Ichimura, Austern, and Vincent [ Phys. Rev. C 32, 431 (1985)], for the nonelastic breakup. These calculations indicate that most of the ${}^7\mathrm{Li}$ yields are due to nonelastic breakup contributions (transfer), whereas elastic breakup plays a minor role.
