The strong incident-angle dependence of the phase of complex reflectivity causes a shift of the reflected beam from the geometrically expected path. This effect, known as the Goos-Hanchen effect in the visible region, was observed for Bragg-case diffraction in the hard X-ray region. The shift was found to be in good agreement with the theory.
