TOTAL KINETIC ENERGIES AND NUCLEAR-CHARGE YIELDS IN THE FISSION OF RELATIVISTIC U-233 SECONDARY PROJECTILES

For isotopically separated secondary beams of U-233 delivered by the S IS-FRS facility at the GSI, fission-in-flight induced by electromagnet ic excitations in a lead target and by nuclear interactions in a plast ic target at beam energies of about 420.A MeV was observed. The nuclea r-charge yields and the total kinetic energies released during the fis sion process as a function of the nuclear charge of the fission fragme nts were measured. The results are compared to data measured by therma l-neutron-induced fission. (C) 1997 Elsevier Science B.V.
