Velocity and angular distributions of neutrons associated with light and heavy groups of fission fragments from spontaneous fission of Cf/sup 252/ were measured. The results can be accounted for within about 10 to 20% by assuming isotropic evaporation from moving fragments. Leastsquared fits to the data were made on this assumption and yield accurate values for the numbers of neutrons emitted by the light and heavy fragments and for their energy spectra. The energy spectra were analyzed in terms of effective temperatures of the fragments. A discussion of the systematic differences from simple evaporation theory is given. (auth)
