Elastic and Inelastic Neutron Cross Sections for Boron-10 and Boron-11

Neutron cross sections have been measured for ¹⁰B and ¹¹B. Elastic angular distribution data for ¹⁰B are reported for incident neutron energies of 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, and 14.0 MeV. Elastic scattering data and inelastic scattering data for states at excitation energies of 2.14, 4.46, and 5.04 MeV in ¹¹B are reported for incident neutron energies of 8.0, 9.0, 9.7, 9.9, 11.0, 12.0, 13.0, and 14.0 MeV. Legendre coefficients for angular distributions are obtained. All data are corrected for finite geometry and multiple scattering effects through a light-element Monte Carlo code. The angle integrated data for ¹¹B are in disagreement with ENDF/B-IV for the higher neutron energies.
