Elastic scattering and total reaction cross sections for the {sup 8}Li+{sup 12}C system

The elastic-scattering angular distribution for {sup 8}Li on {sup 12}C has been measured at E{sub LAB}=23.9 MeV with {sup 8}Li 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 doub...

Description
Summary:The elastic-scattering angular distribution for {sup 8}Li on {sup 12}C has been measured at E{sub LAB}=23.9 MeV with {sup 8}Li 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 {sup 12}C({sup 8}Li,{sup 9}Be){sup 11}B reaction was also measured at the same energy. The spectroscopic factor for the 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 {sup 6,7,8}Li isotopes on {sup 12}C was performed as a function of energy.
