摘要：

The number of neutrons emitted in the spontaneous fission of Cf-252 has been measured, using a large Gd-doped liquid scintillator tank. A total of 1.7 x 10(7) Cf-252 fission events were assayed, and the correlations between the number of neutrons emitted by the fission fragments and the total kinetic energy (TKE) released in a particular fission event were investigated. From these correlations, spontaneous-fission parameters were derived and compared to exit-channel predictions given by the multi-modal random neck-rupture model of Brosa and co-workers.
