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. WebJul 29, 2024 · The absolute activities of these nuclides were determined by BETA - and gamma counting techniques, and the cumulative fission yields were calculated relative to /sup 140/Ba. The peak-to-valley ratio was found to be effectively constant; thus, the average photon-energy-inducing fission is essentially equal for all three energies studied.
