<Lester Germer> and <Clinton Davisson> observed <electron diffraction> from a <nickel> crystal. The intensity of scattered <electrons> varied strongly with direction and incident <electron> <energy>, as expected when a crystal's periodic structure acts on a wave. Agreement between the inferred wavelength and the <de Broglie wavelength> connected a particle's <momentum> with observable <interference>. The experiment made <electron> wave behavior a measured property of a material-scattering apparatus.<Diffraction of Electrons by a Crystal of Nickel by C. Davisson and L. H.
