Total kinetic energies and nuclear-charge yields in the fission of relativistic 233U secondary projectiles

For isotopically separated secondary beams of 233U delivered by the SIS-FRS facility at the GSI, fission-in-flight induced by electromagnetic excitations in a lead target and by nuclear interactions in a plastic target at beam energies of about 420 · A MeV was observed. The nuclear-charge yields and the total kinetic energies released during the fission process as a function of the nuclear charge of the fission fragments were measured. The results are compared to data measured by thermal-neutron-induced fission.
