Weburanium-238. The production of curium-244 is found to increase with about the fourth power of the burnup. The neutron emission is therefore very sensitive to variations in burnup. Cesium-137, the major gamma emitter after five years of cooling, is produced as a fission product. Its production is essentially a linear function of burnup. Fork System WebAug 27, 2014 · The number of prompt neutrons emitted in the fission event have been measured separately for each complementary fragment in coincidence with fragment mass and kinetic energies in spontaneous fission of 252 Cf, 244 Cm and 248 Cm.
