Compton Scattering is the 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 effect was at first observed by Arthur Holly Compton in 1923 at Washington University in St. Louis. Compton was rewarded the 1927 Nobel Prize in Physics for this discovery.

Arthur H. Compton treated the x-ray photons as particles and applied conservation of energy and conservation of momentum to the collision of a photon with a stationary electron.[1]. He used the Planck relationship and the relativistic energy expression to derive the standard Compton formula:

Here, Δλ denotes the difference between the wavelengths of the incoming and the scattered ray, while θ is the angle of scattering.

The probability for Compton scattering is approximately proportional to Z, and for energies greater than 500 keV approximately proportional to .[2]
