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. WebA Monte-Carlo method for the generation of correlation and covariance matrices for independent and cumulative fission yields has been developed. The method uses a constrained Monte-Carlo resampling structure in order to vary evaluated fission yield libraries in a way that meets basic conservation principles. This results in the generation …
WebJan 30, 2024 · Cumulative Yield: The probility that a given isotope will form directly (via independent yield) and indirectly by decay of a parent nuclide. \(A + n \rightarrow B + C\) ... Note: Sum of total yields for binary fission will be 200%. Relative Yield. Relative Yield \( \gamma_i\) is the ratio of absolute yields formed in fission, which can be ... 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.
