Abstract
Abstract The apparent absorption of high energy electrons in crystals due to elastic scattering has been considered by a number of authors, and a numerical estimate of the magnitude of this effect by Hall and Hirsch (1965 a), based upon an approximate theory, suggests that this process makes a negligible contribution to the total. The approximation made in that treatment of considering the scattering kinematically is discussed and its effect upon the predictions of the simple theory investigated by performing some numerical calculations based upon the dynamical theory of diffraction. It appears that the mean apparent absorption due to this cause is overestimated by the simple theory, but that in special cases the apparent absorption can be much larger than the mean value.
