Collision process between a gamma ray and a bound atomic electron where only part of the gamma-ray energy is transferred to the electron. The probability for Compton scattering is approximately proportional to Z, and for energies greater than 500 keV approximately proportional to 1/Egamma
interaction process for x or gamma radiation where an incident photon interacts with an orbital electron of an atom to produce a recoil electron and a scattered photon with energy less than the incident photon.
gamma ray photons will bounce off electrons as they pass through the earth and atmosphere, reducing their energy and then being detected by radiometric sensors at lower energy levels. See also stripping.
In physics, Compton scattering or the Compton effect, is the decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, when it interacts with matter. Inverse Compton scattering also exists, where the photon gains energy (decreasing in wavelength) upon interaction with matter. The amount the wavelength increases by is called the Compton shift.
