Abstract
The University of Lowell high-resolution time-of-flight spectrometer has been used to measure angular distributions and 90-deg excitation functions for neutrons scattered from 238U in the energy range from 0.9 to 3.1 MeV. This study was limited to the elastic and the first two inelastic groups, corresponding to states of 238U at 45 keV (2+) and 148 keV (4+). Angular distributions were measured at primary neutron energies of 1.1, 1.9, 2.5, and 3.1 MeV for the same three neutron groups. Whereas our elastic data are in fair agreement with the evaluation in the ENDF/B-IV file, there is substantial disagreement between our inelastic measurements and the evaluated cross sections.Keywords
