Anomalous Scattering and Null‐Domain Ghost Corrections for Fibre Textures

The practical applicability of anomalous scattering and null-domain ghost correctionsfor fibre textures is theoretically evaluated. For a hypothetical asymmetric orientationdistribution of quartz-like BPO 4 highly absorpting crystals, slightly asymmetricanomalous scattering pole figures are predicted. On the basis of projection relationsamong orientation distribution functions and inverse pole figures, the specialcharacteristics of the null-domain method for fibre textures are discussed, with thesuggestion of a practical procedure to estimate (in favourable cases) an upper limitfor ghosts effects.
