Uranium-236 neutron absorption is measured as a function of neutron time of flight from 20 eV to 1 MeV. The neutron flux is monitored with a 6Li glass scintillator. Average cross sections from 3 keV to 1 MeV are derived. Estimated uncertainties are <5% below 600 keV and increase to 9.5% at 1 MeV. From 20-eV to 4.2-keV neutron energy, 293 resonance peaks are parameterized.
