Abstract
A. D. BOOTH has suggested1 that a study of the diffuse reflexions in X-ray diffraction photographs should give information as to the phase-angles of the Bragg reflexions. In particular, in the case of a centro-symmetrical structure, for which the phase-angles of the reflexions are all 0° or 180°, a streak of diffuse reflexion joining two Bragg reflexions would indicate that there can be no change of sign in the structure factor between the Bragg reflexions, and that these two reflexions must therefore have the same phase-angle.
