Abstract
The isotopic distributions and recoil velocities of the fission fragments produced in the spallation reaction 208Pb+p at 500 A MeV have been measured using the inverse kinematics technique. The shapes of the different distributions are found in good agreement with previously published data while the deduced total fission cross-section is higher than expected. From the experimental data, the characteristics of the average fissioning system can be reconstructed in charge, mass and excitation energy and the number of post-fission neutrons can be inferred. The results are also compared to different models describing the spallation reaction.
