The influence of the dispersion and vertical divergence on the half width of the reflection curves was investigated using a double‐crystal arrangement where the second crystal could be rotated about an axis parallel to the beam reflected by the first crystal. The experimentally measured dependence of the half width of the reflection curves on the angle of rotation φ is accurately confirmed by geometrical considerations.
