Diffraction of Electrons at a Polycrystalline Lattice (Debye-Scherrer Diffraction) Experiment

The experiment P6.1.5.1 demonstrates diffraction of electrons at polycrystalline graphite. As in the Debye-Scherrer method with x-rays, we observe diffraction rings in the direction of radiation which surround a central spot on a screen. These are caused by the diffraction of electrons at the lattice planes of microcrystals which fulfill the Bragg condition

As the graphite structure contains two lattice-plane spacings, two diffraction rings in the first order are observed. The electron wavelength

is determined by the acceleration voltage U, so that for the angular aperture of the diffraction rings we can say
