What does your textbook say about 11.9 DAVISSON AND GERMER EXPERIMENT?
The wave nature of electrons was first experimentally verified by C.J. Davisson and L.H. Germer in and independently by G.P. Thomson, in , who observed diffraction effects with beams of electrons scattered by crystals. Davisson and Thomson shared the Nobel Prize in for their experimental discovery of diffraction of electrons by crystals. The experimental arrange- ment used by Davisson and Germer is schematically shown in Fig. . . It consists of an electron gun which comprises of a tungsten filament F, coated with barium oxide and heated by a low voltage power supply
