Resumo
Cross-sections for fragments produced by the fission reaction induced by accelerated Li-7 ions impinged into an Pb-nat target at 245 MeV were obtained. We have applied the induced-activation method in off-line analysis. The analysis of charge and mass distributions of fission products allowed the determination of the total fission cross-section for the Li-7+Pb system. The recoil technique ({''}thick target - thick catcher{''}), based on the two-step model mathematical formalism, is used to determine the kinematics characteristics of reaction products. The analysis concerning transferred linear momentum provided information on the initial projectile-target interaction, and is compared with proton-induced fission measurements. (AU)
