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