Abstract
The \(^8\)Li + \(^9\)Be quasi-elastic angular distribution and the \(^{9}\)Be(\(^{8}\)Li\(,^{7}\)Li)X inclusive reaction have been measured at E\(_{\textrm{Lab}}=23.8\) MeV bombarding energy using the RIBRAS facility. In addition to the \(^8\)Li scattering peak, a large yield of \(^7\)Li particles has been observed in the identification spectra, presenting a wide energy distribution centered around and below the energy of the \(^8\)Li quasi-elastic peak. The \(^7\)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 \(^7\)Li+n and the \(^9\)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 \(^{7}\)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.
