Resumo

The elastic-scattering angular distribution for Li-8 on C-12 has been measured at E-LAB = 23.9 MeV with Li-8 radioactive nuclear beam produced by the Radioactive Ion Beams in Brazil facility. This angular distribution was analyzed in terms of optical-model with Woods-Saxon and double-folding Sao Paulo potential. The roles of the breakup and inelastic channels were also investigated with cluster folding and deformed potentials, respectively, through coupled-channels calculations. The angular distribution for the proton-transfer C-12(Li-8, Be-9)B-11 reaction was also measured at the same energy. The spectroscopic factor for the < Be-9|Li-8 + p > bound system was obtained and compared with shell-model calculations and with other experimental values. Total reaction cross sections for the present system were also extracted from the elastic-scattering analysis. A systematic of the reduced reaction cross sections obtained from the present and published data on Li-6,Li-7,Li-8 isotopes on C-12 was performed as a function of energy. (AU)
