Abstract
The results of published calculations on the prompt nuclear cascade and nuclear evaporation processes are combined with some assumptions regarding the nuclear fission process and fission widths to calculate the average neutron-to-proton ratios of fission products from Th + 8-Mev protons, Th + 87-Mev protons, and U + 450-Mev protons. Comparison of the results with experimental data indicates that the fission charge distribution mode characterized by the equal charge displacement hypothesis, hitherto considered a low energy phenomenon, persists in uranium and thorium up to the highest energy studied. There is also some evidence that fission occurs in excited heavy nuclei before complete de-excitation by particle emission, in agreement with other experimental work.
