In quantum mechanics, the Stern–Gerlach experiment, named after Otto Stern and Walther Gerlach, is a celebrated experiment in 1922 on deflection of particles, often used to illustrate basic principles of quantum mechanics. It can be used to demonstrate that electrons and atoms have intrinsically quantum properties, and how measurement in quantum mechanics affects the system being measured.

the Davisson-Germer experiment provided a critically important confirmation of the de Broglie hypothesis that particles, such as electrons, could behave as waves. More generally, it helped cement the acceptance of quantum mechanics and of Schrödinger's wave equation.

In 1927 at Bell Labs, Clinton Davisson and Lester Germer fired slow moving electrons at a crystalline nickel target. The angular dependence of the reflected electron intensity was measured, and was determined to have the same diffraction pattern as those predicted by Bragg for X-Rays.

This experiment, like Arthur Compton's experiment which gave support to the particle-like nature of light, lent support to de Broglie's hypothesis on the wave-like nature of matter and completed the wave-particle duality hypothesis, which was a fundamental step in quantum theory.
