Abstract
A statistical model is used with parameters obtained by fitting 232U(n ,f) through U-236(n,f) and U-238(n,f) cross-section data to determine the U-237(n,f) fission cross section in the neutron energy range of 0. 5 to 20 MeV. Below an incoming neutron energy of 0.5 MeV, the cross se ction is extrapolated using the neutron energy dependence of the U-235 (n,f) reaction. The calculated values to experimental U-237(n,f) cross -section data are compared, and some adjustments are made to the calcu lated values to obtain a better fit to the existing data.
