摘要: Abstract Fission fragment mass and kinetic energy distributions mass-versus-energy correlations have been measured for the thermal neutron induced fission of 239Pu 235U. Unwanted events were eliminated by a coherence test based on time flight. The global distribution shows much weaker fine structure than However, with high total this becomes more prominent yield 135 dominates compared to 134 Moreover, prolate deformation 102 in ratio 235U is compatible data. results show that EK(μH), hence EL and/or EH regions low tails produced act fission. Furthermore, data suggest most proton pairs are broken after effective determination nascent fragments probably just before scission itself.
