A method is described which permits absorption coefficients in the dynamical theory of electron diffraction to be obtained for non‐column approximation calculations of stacking fault contrast. The method is based on the use of the exact form of the dynamical equations which include the wave vector change due to the imaginary part of the lattice potential. The results obtained show that absorption coefficients of the Bloch waves excited at the fault are quite different from the absorption coefficients of the Bloch waves excited at the entrance surface.
