Abstract

A general kinematic treatment of x-ray scattering by crystals with dislocations was developed by Darwin [1], Krivoglaz et al. [2], Warren [3], and Wilkens [4]. This approach is widely used for the analysis of dislocation substructure and local rotations in single crystals measured by means of rocking curves [5][13]. The main disadvantage of the rocking curve technique is the need to rotate the sample; rotations introduce uncertainties in the real space coordinates of the scattering volume[14]. Laue white beam measurements however are performed at a fixed orientation of the sample. Special instrumentation [15] makes it possible to correlate different points of the Laue intensity with diffraction from regions within the crystal (Fig. l a).
