Abstract: 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 ^U and ^U compared to intranuclear cascade and statistical
model predictions.
(235,238u(n,f) cross section, 232Th, 233,234,236U, 237Np, 239pu ratio to 235U,
fission, intranuclear cascade model, pre-equilibrium-statistical model)
