FISSION OF TH-232 AT ENERGIES UP TO 90 MEV

[[abstract]]©1981 APS - In a recent work, the yields of spallation residues from 8-90 MeV proton induced fission of 232Th were reproduced by exciton model calculations to which a fission option had been added. This allowed evaluation of the spectrum of fissioning nuclei. In this work, an extension of that calculation to the properties of the fission products is presented. Dividing the fissioning nuclei according to their fissionability, an approach is introduced which accounts for the percentage of symmetric and asymmetric fission, allows calculation of the most probable charge for a given fission product mass chain, and evaluates the numbers of pre- and post-fission neutrons. A comparison of the results of this calculation is made with extensive amounts of experimental data, and the implications of the calculation discussed.[[fileno]]2060216010061[[department]]醫環
