%X Two theories are widely used to describe the intensities observed in electron or X-ray diffraction by crystals. The "kinematical theory" treats the crystal as perturbation and is therefore valid only for sufficiently small crystals. For larger crystals one has to take into account the multiple scattering of the incident wave. This problem, which is simplified substantially by the periodicity of the crystal, has been dealt with first by Darwin in 1914 [1). More fundamentally the problem has been treated in a series of papers by Ewald in 1917 (2) and later on by von Laue I3 J . These papers form the basis of the socalled "dynamical theory", which has been extended further by Bethe [4] for the case of electron diffraction.
