Editing Prompt neutron (section)

==Importance in nuclear fission basic research==

The   standard deviation of the final kinetic energy distribution as a function of mass of final fragments from low energy  fission of uranium 234 and uranium 236, presents a peak around light fragment masses region and another on heavy fragment masses region. Simulation by Monte Carlo method of these experiments suggests that those peaks are produced by prompt neutron emission.<ref>R. Brissot, J.P. Boucquet, J. Crançon, C.R. Guet, H.A.
