WebJan 14, 2016 · Comparison of relative fission yields determined in this study (colored symbols) with England and Rider (gray symbols) and the JEFF-3.1 database (white symbols). All yields are normalized to the cumulative yield of 138 Xe given by England and Rider and are shown with 1σ (darker) and 2σ (lighter) uncertainties. WebFeb 1, 2024 · The calculated fission observable quantities, such as the energy-dependent fission yields, and prompt and delayed neutron yields, are compared with available experimental data. We also study a possible impact of the second chance fission opening on the energy dependence of the delayed neutron yield by extrapolating the calculation.
