Diffraction Effects of Crystals with Deformation Faults

Abstract
The theory of ideal paracrystals is applied to the problem of the diffraction effects of face-centered cubic crystals with deformation faults (as distinct from growth faults) in the plane (111). It is shown that the formulas given by Paterson are more easily deduced with the help of this theory and the problem of Paterson is only a special case (e.g., the case of infinitely large crystals and of coordination statistics given by peak functions) of the general deformation effects postulated in this theory.
