This experiment was replicated by Stern and Estermann using helium and lithium fluoride. It was also verified by a contemporaneous experiment that passed a collimated beam of particles through a thin gold foil. Unlike the Thomson-Reid experiment, this experiment used thermionic emission from a tungsten filament as a source and a Faraday cup on a rotating arm as a detector. This experiment benefited from an accident that caused the sample surface to oxidize and (*) recrystallize. The experimenters expected to observe specular reflection due to the sample's rough surface, but instead they observed a strong signal at 50 degrees and 54 electronvolts. In this experiment, scientists fired electrons at a block of nickel and measured the resulting diffraction pattern. For 10 points, name this experiment which confirmed the de Broglie hypothesis by demonstrating that electrons have wave-like properties.
