Compton scattering

(komp -tŏn) (Compton effect) An interaction between a photon of electromagnetic radiation and a charged particle, such as an electron, in which some of the photon's energy is given to the particle. The photon is therefore reradiated at a lower frequency (i.e. with a lower energy) and the particle's energy is increased. In inverse Compton emission the reverse process takes place: photons of low frequency are scattered by moving charged particles and reradiated at a higher frequency.

Compton scattering has recently attracted significant attention from both the experimental and theoretical points of view (Bergstrom and Pratt 1997, Anastassopoulous et al.
The purpose of this paper is to answer the following question in terms of concepts of classical relativistic mechanics: How is Compton scattering altered if we replace the photon by a particle of zero rest mass and negative energy, and apply the conservation of 4-momentum?
At the interaction point a laser beam interacts with the X-ray beam producing electron due to Compton scattering effect that is delivered to the experimental station.
As they move around inside the supernova, the gamma rays collide with electrons in a process called Compton scattering, by which their energies and frequencies are diminished until they fall into the X-ray range.

Profile attenuation correction is an innovative Siemens solution to the problematic effects of attenuation in clinical nuclear imaging--the reduction of detectable emissions due to the photoelectric absorption and compton scattering of photons as they pass through organs and other tissue.
