Nuclear Fission Processes and Data–Panel

Since fission was first discovered, there have been many advances in our knowledge of the fission process and nuclear data. This session is devoted to recent advances in nuclear fission theory and the experiments performed to advance this knowledge. This includes discussion on data fission cross-sections, fission fragment yields, prompt fission neutrons and photons, the evaluation of nuclear data, and their use in Monte Carlo transport simulations.
