X‐Ray Diffraction by a Crystal Containing a Translation Fault

Abstract

Abstract We consider the diffraction of X‐rays by a bicrystal consisting of a thick part and a thin part separated by a rigid body translation. Both parts have identical lattice parameters. This simple model and the plane‐wave diffraction theory developed herein describe very well the contrast and geometry of the fringes obtained in X‐ray diffraction topographs of some silicon crystals bombarded by monoenergetic ions.
