Compton, Arthur Holly (1892–1962)




Arthur Holly Compton
American physicist who discovered the Compton effect (1923), thus providing evidence that X-rays could act as particles as predicted by quantum theory. Compton found that when monochromatic X-rays were scattered by light elements, some of the scattered radiation was of longer wavelength, i.e., of lower energy than the incident. Compton showed that this could be explained in terms of the collision between an X-ray photon and an electron in the target. For this work he shared the 1927 Nobel Prize in Physics with C. T. R. Wilson.
