Measurement of the differential elastic and inelastic neutron scattering cross sections of carbon from 8. 0 to 14. 5 MeV
Measurements of differential cross sections for fast neutrons scattered by carbon are presented for 14 incident neutron energies between 8.0 and 14.5 MeV. The measurements were performed with the four-detector neutron time-of-flight facility of the Centre d'Etudes de Bruyeres-le-Chatel tandem Van de Graaff accelerator. The angular distributions for elastic and inelastic scattering to the first excited level of /sup 12/C were obtained over the angular range from 10 to 160/sup 0/. The experimental uncertainties vary from 7 to 15% for the differential elastic scattering cross sections and from 8 to 22% for the differential inelastic scattering cross sections. These measurements partially fill in an energy range that was previously characterized by a lack of data. The angle-integrated cross sections are compared to the evaluated values of ENDF/B, and significant discrepancies are shown. The present data were included in an evaluation work on carbon carried out in this laboratory. The consistency of total cross-section measurements with our data and other partial cross sections is discussed.
