An absolute determination of the average number of neutrons, , emitted in the spontaneous fission of Cf/sup 252/ was made by counting the fission neutrons in a large liquid scintillator. The detection efficiency of this counter was measured as a function of neutron energy. Well-collimated neutrons were scattered into the scintillator by an anthracene crystal, which detected the corresponding recoil protons. Pulse-shape discrimination was employed to eliminate -ray background. The average number of prompt neutrons emitted per Cf/sup 252/ fission was found to be 3.799 surface proces 0.034. (auth)
