The aim of this work is to present an experimental procedure to measure directional Compton profiles by means of electron energy-loss spectroscopy in the transmission electron microscope. In order to obtain unique profiles with a well defined orientation in momentum space a symmetric two-beam scattering geometry taking advantage of crystal symmetry was developped. Measurements on single crystal silicon are discussed in comparison to results of other Compton scattering techniques and theoretical calculations.
