Neutron spectra in uranium depleted in the ²³⁵U isotope are analyzed with ENDF/B-III data, accounting for high-order anisotropic scattering. Two principal conclusions are made. First, changes made to inelastic scattering data relative to earlier ENDF/B files are not effective in reducing discrepancies between calculated and measured spectra. Second, changes made to unresolved capture data lead to significant improvement in the relation between calculation and experiment.
