Is the border surface of a crystal indeed the weakest point of the dynamical theory of diffraction?
In Laue's dynamical theory of diffraction, the boundary conditions claim to introduce a mathematical plane instead of the discrete atomic surface of the crystal. This assumption is analysed from the point of view of Ewald's theory based on the microscopic discrete model of a crystal, where no boundary conditions are needed.
