DIFFERENTIAL ELASTIC AND INELASTIC SCATTERING OF 7- TO 15-MeV NEUTRONS FROM BERYLLIUM.
Differential cross sections are reported for elastic and inelastic scattering of neutrons from beryllium. Source neutrons were provided by the D(d,n)**3He reaction at energies from 7 to 15 MeV in 1-MeV steps. Scattered neutrons were observed over a flight path of 4 m at angles ranging from 25 to 160 deg in 5-deg increments. The integrated elastic scattering cross sections agree well with the ENDF/B-IV cross-section set. The inelastic scattering cross sections are for the sum of the 1. 69-, 2. 43-, 2. 8-, and 2. 06-MeV-state cross sections and fall below the ENDF/G-IV predictions. Inelastic scattering to the 2. 43-MVstate in **9Be accounts for less than half of the total **9Be(n,2n) cross sections above 8 MeV.
