The experiment 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 microcrystal, 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.
