Huang diffuse scattering from interstitials in a general orthorhombic and tetragonal lattice
Using the continuum theory of linear elasticity, Huang diffuse scattering (HDS) has been calculated from self-interstitials in a general orthorhombic and tetragonal lattice. Various defect configurations are represented according to the point group symmetry of the defect site. The contribution toHDS from all possible equivalent orientations (assumed to be equally populated) of the defect configuration is averaged. The limitations ofHDS in discriminating between defect configurations having the same long-range symmetry are discussed, considering some special cases.
