Anisotropy in the scattering of thermal neutrons from beryllium oxide has been investigated. Elastic differential scattering cross sections have been calculated by replacing the δ function occurring in the expression by a Gaussian. The effect of changing the width of the Gaussian on the differential cross section has also been studied. Anisotropy in inelastic scattering has been calculated for coherent one-phonon and incoherent one- and two-phonon processes. Using these differential cross sections, we have calculated the energy distribution of neutrons scattered along different directions by a beryllium oxide slab and these results are compared with corresponding measured results. The agreement between the two sets of results is found to be good.
