Monte Carlo Hauser-Feshbach Modeling of Prompt Fission Neutrons and Gamma Rays

摘要

The decay of fission fragments is studied throughMonte 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.
