The dynamical theory of electron diffraction in a thin foil with a stacking fault is reconsidered from the point of view of Bloch wave scattering at the stacking fault. A formalism for many‐beam systematic diffraction is developed from which a close relationship between the stacking‐fault‐induced transformation of the various Bloch waves and the corresponding transformation of the excitation amplitudes of the Bloch waves emerges. It is suggested that the present formulation shows more clearly the nature of the scattering process involved.
