A peculiar kind of intensive X‐ray standing wave is analytically shown to exist. Such an X‐ray interference field is localized in the vicinity of a surface of a crystalline superlattice and its amplitude decays exponentially in both directions perpendicular to the surface. The appearance of the standing wave is accompanied by a deep dip in a chosen Bragg peak of the superlattice.
