Dynamical Theory of Electron Diffraction (Two-Beam Approximation)
The main assumption in the kinematieal theory is that amplitudes of diffracted waves are negligible as compared to the amplitude of the incident electron wave. At the same time, electrons interact with matter much more strongly than X-rays. Therefore, multiple scattering effects appear in the crystal under certain conditions, so that amplitudes of diffracted waves might become comparable to the amplitude of the incident beam.
