Hindered Prompt-Neutron Evaporation in Surrogate Reactions for ${}^{239}$Pu(n,f)

D. Ramos, M. Caamano, F. Farget +18

Isotopic fission-fragment distributions of ${}^{240}$Pu have been measured, for the first time, as a function of the initial excitation energy, and the prompt neutron multiplicity ha…
