Abstract

Cross-sections for fragments produced by the fission reaction induced by accelerated ⁷Li ions impinged into an ^natPb target at 245MeV 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 ⁷Li+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.
