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