Effect of temperature on dynamical electron diffraction intensities

Abstract

The temperature dependence of dynamically influenced electron diffraction intensities of a polycrystalline aluminum foil was measured in the temperature range 150–800°K. It is shown that the experimentally determined effective Debye Waller factors exp (-α gM g) for these reflections (g) are in good agreement with theoretical calculations, based on the dynamical theory of electron diffraction.
