Compton effect

Physics

The reduction in the energy of high-energy (X-ray or gamma-ray) photons when they are scattered by free electrons, which thereby gain energy. The phenomenon, which was first observed in 1923 by the US physicist A. H. Compton, occurs when the photon collides with an electron; some of the photon’s energy is transferred to the electron and consequently the photon loses energy h(ν‎₁ − ν‎₂), where h is the Planck constant and ν‎₁ and ν‎₂ are the frequencies before and after collision. As ν‎₁ > ν‎₂, the wavelength of the radiation increases after the collision. This type of inelastic scattering is known as Compton scattering and is similar to the Raman effect. See also inverse Compton effect.

Astronomy

The change in wavelength and direction of an X-ray or gamma-ray photon when it collides with a particle, usually an electron. Some of the photon’s energy is transferred to the particle and the photon is reradiated at a longer wavelength. The effect is used to detect gamma rays by converting the photon to one of lower energy, which can be more easily detected by, for example, a proportional counter. The effect was discovered in 1923 by the American physicist Arthur Holly Compton (1892–1962). See also inverse compton effect.
