Neutron time-of-flight quasi-differential high energy scattering measurements of uranium-238 and natural iron were made at the Rensselaer Polytechnic Institute (RPI) Gaerttner Linear Accelerator Center. Data from the measurements were compared to evaluated nuclear data libraries using MCNP to identify energy-angle discrepancies from 0.5 to 20 MeV, and elastic-to-inelastic scattering ratios were generated using the detectors’ measured response functions from 1.4 to 2.0 MeV. A new analysis technique was applied to pre-existing uranium-238 data to derive uranium-238 fission response functions at several energies. Combining the scattering and fission response functions has allowed for the calculation of scattering-to-fission ratios for uranium-238. These response functions can also be used to isolate the scattering contribution and to constrain nuclear data physics models used in the development of evaluated nuclear data libraries.
