EVENT-BY-EVENT MODELING OF PROMPT NEUTRONS AND PHOTONS FROM NEUTRON-INDUCED AND SPONTANEOUS FISSION WITH FREYA

摘要

The fast event-by-event fission code FREYA generates large samples of complete fission events. Using FREYA, it is possible to obtain the fission products as well as the prompt neutrons and photons emitted during the fission process, all with complete kinematic information. We can therefore extract any desired correlation observables. Concentrating on ~(239)Pu(n,f), ~(240)Pu(sf) and ~(252)Cf(sf), we compare our FREYA results with available data on prompt neutron and photon emission and present predictions for novel fission observables.
