The Li + Be quasi-elastic angular distribution and the Be(LiLi)X inclusive reaction have been measured at E MeV bombarding energy using the RIBRAS facility. In addition to the Li scattering peak, a large yield of Li particles has been observed in the identification spectra, presenting a wide energy distribution centered around and below the energy of the Li quasi-elastic peak. The Li angular and energy distributions have been obtained and analysed assuming that these particles stem from two different mechanisms: (i) the elastic breakup (EBU), in which the projectile dissociates into Li+n and the Be target remains in its ground state and (ii) the nonelastic breakup (NEB) which accounts for absorptive processes between the neutron and the target, including the neutron transfer. The Li angular and energy distributions have been analyzed by the Ichimura, Austern and Vincent (IAV) model for NEB, and the Continuum-Discretized Coupled-Channels (CDCC) method for the EBU. The theoretical results are in good agreement with the experimental data.
