The prompt- and delayed-neutron multiplicities for photofission of the eight isotopes, ²³²Th, ²³³U, ²³⁴U, ²³⁵U, ²³⁶U, ²³⁸U, ²³⁷Np, and ²³⁹Pu, have been measured using bremsstrahlung with end-point energies ranging from 8 to 13 MeV. The measured multiplicities are compared with those from the same compound nucleus formed in neutron-induced fission where such data exist.
