Abstract
Theoretical calculations by Huang show that elastic singularities in a crystalline lattice should produce four specific x-ray scattering effects which include diffuse scattering and an artificial temperature factor. All four of the effects are present in neutron-irradiated crystals of boron carbide, diamond, silicon carbide, and magnesium oxide. Thus the model and calculations of Huang are qualitatively confirmed. It is suggested that it may be possible to determine more precisely the nature of the lattice distortions around localized static lattice defects from a detailed study of the diffuse scattering.
