WebDec 16, 2024 · where K \(_{f}\) is the scaling factor [], V \(_{LDM}\) is the fission barrier from the finite-range rotating LDM potential, and E \(^{*}\) is the CN excitation energy. In our analysis, ER and fission cross-sections are fitted with the adjustment of scaling factor K \(_{f}\) in the fission barrier. In this work, shell correction is applied only to the ground … WebSome of the fission products generated during nuclear reactions have a high neutron absorption capacity, such as xenon-135 (microscopic cross-section σ = 2,000,000 barns (b); up to 3 million barns in reactor conditions) and samarium-149 (σ = 74,500 b). Because these two fission product poisons remove neutrons from the reactor, they will affect the …
