“…[4], this result leads to better ν calc (A) but worsens ǫ calc (A), and should only be viewed as a sensitivity test for the Monte Carlo simulations. Note that the Monte Carlo calculated PFNS lie well within the current experimental as well as evaluated uncertainties [22]. Figure 5 shows the quantity −dν/dT KE as a function of the fragment mass.…”

Abstract. The decay of fission fragments is studied through Monte Carlo Hauser-Feshbach model calculations taking into account the competition between the emissions of prompt fission neutrons and gamma rays. The importance of initial excitation energy and spin distribution in the primary light and heavy fragments is demonstrated through comparison with experimental data. Excitation energy sorting mechanisms at scission are discussed in the light of these advanced simulations. Preliminary results on prompt fission gamma rays are also reported.
