Contribution

It presents new experimental data on 7Li-induced fission of lead, including charge, mass distributions, and kinematic analysis, using the induced-activation and recoil techniques.

Findings

Total fission cross-section determined for 7Li+Pb system

Charge and mass distributions of fission fragments characterized

Comparison of linear momentum transfer with proton-induced fission

Abstract

Cross-sections for fragments produced by the fission reaction induced by accelerated 7Li ions impinged into an natPb 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 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. Analysis concerning transferred linear momentum provided information on the initial projectile-target interaction, and is compared with proton-induced fission measurements.
