Measured near-equilibrium delayed neutron spectra produced by fast-neutron-induced fission of /sup 232/Th, /sup 233/U, /sup 235/U, /sup 238/U and /sup 239/Pu. [130 to 1500 keV, energy spectra]

The near-equilibrium energy spectra of the delayed neutrons associated with fast-neutron-induced fissions of /sup 232/Th, /sup 233/U, /sup 235/U, /sup 238/U and /sup 239/Pu are reported over the energy range 30 keV to 1500 keV. The fission source spectrum approximated a prompt fission spectrum. A significant fraction of delayed neutrons were found to exist at energies below 100 keV and peaks in the spectra are in agreement with peaks reported by others. Comparisons with existing measurements show agreement at energies above 150 keV but have significant differences at energies below this value.
