Quasi-dynamical electron diffraction - a kinematic type of expression for the dynamical diffracted-beam amplitudes
It is shown that to a good approximation the dynamical diffracted electron-beam amplitudes may be expressed in a form that is identical to that of the kinematic theory of electron diffraction. The validity of this approximate form of the dynamical electron diffraction is illustrated for thin films of GaAs and Au crystals, and its implications in electron crystallography for structural determination and refinement are discussed.
