The interaction of 538 MeV 56Fe with 238U

Binary coincident fragments from the 56Fe+238U reaction at 538 MeV have been studied. Fragment energies were measured and fragment masses determined by a kinematical method. Three types of event are defined by suitable adjacent limits in the mass versus energy event space. The angular distributions of cross section, energy and mass have been determined for each event region and particular attention paid to that part containing possible fissions following complete fusion. The total reaction cross section consists of about 50% of binary fragmentation channels. The remaining channels correspond to a ternary process of heavy recoil fission. (Auth.)
