www.phys.utk.eduenergy and momentum are transferred to the charged particle while the photon moves off with a reduced energy and a change of momentum. Generally, the charged particle is an electron considered to be at rest and the photon is usually considered to be an energetic photon such as an X-ray photon or gamma ray photon. In this experiment gamma rays
Compton Scattering - High Energy Physics
pages.hep.wisc.edutered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually written as: ∆λ = λ0 −λ = h mc (1−cosθ) (1) where λ and λ0 are the wavelengths of the incident and scattered photon respectively, and θ is the photon scattering angle.

Attenuation of Radiation - University of Tennessee
www.phys.utk.eduIn pair production, the gamma ray photon’s energy is used to form an electron-positron pair. The rest energy of an electron, and also of a positron, is mc2 where m is the mass of the electron or positron and c is the speed of light. The rest energy of an electron or a positron is 0.511 MeV, so that for an electron-positron pair a minimum ...
