WebNov 29, 2024 · Then, we calculate neutron capture reactions based on the statistical Hauser-Feshbach theory with the photoabsorption cross sections given by QRPA. We find that the capture cross section is enhanced due to the contribution from the low energy M1 transition although the calculated capture cross section still underestimates the … Web[en] A method based on the statistical Hauser-Feshbach theory for the calculation of fission cross sections was described.

WebFeb 1, 2012 · The Hauser-Feshbach statistical theory of nuclear reactions is used to describe the de-excitation of primary fission fragments through the evaporation of prompt neutrons and γ rays. Monte Carlo ... WebDec 28, 2024 · The level density is among the most important statistical nuclear properties. It appears in Fermi's golden rule for transition rates and is an important input to the Hauser-Feshbach theory of compound nucleus reactions. We discuss empirical models of level densities and summarize the main experimental methods used to determine them. The … WebAvailable from UMI in association with The British Library.
