Overview of two deterministic modelings for prompt emission in fission

Published online: 15 December 2021
Two models with a deterministic treatment of prompt emission in fission were developed at the University of Bucharest. Both models work with the same ranges of initial fragments and total kinetic energy and they use the same partition of the total excitation energy at full acceleration based on modelling at scission. The main difference between these modelings regards the prompt emission treatment itself. I.e. the Point-by-Point (PbP) model uses a global treatment of sequential emission while the other modeling is based on an event-by-event treatment of sequential emission. Both models are submitted to a rigorous validation. This paper focuses on model results of different prompt γ-ray quantities, which describe very well the existing experimental data. A new method to calculate prompt γ-ray spectra, including a global treatment based on the distribution of prompt γ-ray energy per quanta, is proposed.
