Prompt fission neutron and γ ray properties as a function of incident neutron energy

The CGMF code provides a complete description of the properties of the prompt neutrons and. rays, emitted before beta decays. It is based on a Monte Carlo implementation of the Hauser-Feshbach statistical model, which provides an accurate phenomenological description of the de-excitation of the fission fragments toward stable configurations via neutron and gamma-ray emissions. This approach allows a detailed description of a large number of observables, such as multiplicity probabilities and correlations between the emitted particles. In this contribution, we briefly review the approach and present selected examples of neutron and gamma-ray observables for neutron incident energies from thermal to 20 MeV, and compare against available data for U-235(n,f) reaction.
