The spontaneous-fission neutron spectrum of 252Cf has been measured from 0.003 to 15.0 MeV by time-of-flight techniques. A hydrogenous liquid scintillator was used as a detector at the higher energies, while a 6Li-loaded glass scintillator was used at the lower energies. The measured spectrum has an average energy of 2.348 MeV. A Maxwellian distribution, N(E)~E12exp (-E1.565), fits the data well for 0.5<E<10.0 MeV. Below 0.1 MeV, N(E) has a √E dependence but with values ~25% larger than those predicted by the extended Maxwellian spectrum. The results are interpreted in terms of a simplified evaporation model.
