The effect of the phases of structure amplitudes appearing in the simultaneous reflexion in electron diffraction as predicted by the dynamical theory has been examined experimentally in convergent-beam electron-diffraction patterns of graphite. Anomalous structures of Kossel-Möllenstedt lines at their cross points have been satisfactorily explained by the theory. Thus, it has been proved that the experimental determination of the phases of structure amplitudes is feasible by the observation of simultaneous reflexion. The phase effects have been found also at the intersecting points of Kikuchi lines.
