Differential Elastic Scattering Cross Sections of Boron-10 for Neutrons of 4 to 8 MeV Energy

Differential neutron cross sections of ¹⁰B for elastic scattering have been measured for ∼30 incident neutron energies between 4 and 8 Me V. Neutrons inelastically scattered from the 0.717-MeV level were completely resolved from the elastic group except at the most forward angles at energies above 7.5 MeV. Generally, the differential cross sections are slowly varying with energy, indicating little resonance structure in this region. These data are consistent with earlier lower energy measurements done at Edwards Accelerator Laboratory and provide detailed data in a region where only sparse data were previously available to evaluators and designers in the nuclear energy field.
