The photodisintegration of 232Th, 233U, 238U, 237Np, and 239Pu has been studied with monochromatic photons produced by neutron capture using the IEA-R1 reactor. The ratios σγf(X)/σγf(238U) (relative fissionability), σγfα (photofission branching ratio), and Γnf (neutron emission and fission competition) are shown to be independent of excitation energy, within the experimental errors, in the 6.73- to 9.72-MeV energy interval. Some correlations of these ratios with Z2/A and (E′f — B′n) are performed, and the results are in reasonable agreement with the theoretical model predictions.
