Available in PDF, EPUB and Kindle. Book excerpt: Until recently there has been very little cross section data for neutron-induced fission in the intermediate energy region, primarily because no suitable neutron source has existed. At Los Alamos, the WNR target-4 facility provides a high-intensity source of neutrons nearly ideal for fission measurements extending from a fraction of a MeV to several hundred MeV. This paper summarizes the status of fission cross section data in the intermediate energy range (En> 30 MeV) and presents our fission cross section data for 235U and 238U compared to intranuclear cascade and statistical model predictions.
