The leading hypotheses for the mechanism of production of these highest-known intensity beams of radiation, are inverse Compton scattering and synchrotron radiation from high-energy charged particles.

Compton scattering is an important effect in gamma spectroscopy which gives rise to the Compton edge, as it is possible for the gamma rays to scatter out of the detectors used.
43.
Generally speaking, there are two major mechanisms : The inverse Compton scattering ( ICS ) and the so-called breakdown of the bead on the wire ( BBW ) mechanism.

The discovery of Compton scattering by Arthur Holly Compton in 1923 convinced most physicists that light was composed of photons, and that energy and momentum were conserved in collisions between electrons and photons.
45.
The distribution arises because of primary gamma rays undergoing Compton scattering within the crystal : Depending on the scattering angle, the Compton electrons have different energies and hence produce pulses in different energy channels.
46.
At energies beyond 100 keV, photons ionize matter increasingly through the Compton effect, and then indirectly through pair production at energies beyond 5 MeV . The accompanying interaction diagram shows two Compton scatterings happening sequentially.
47.
He also pointed out, that the CIB cause a significant attenuation for very high energy electrons, protons and gamma-rays of the cosmic radiation through inverse Compton scattering, photopion and electron-positron pair production.
48.
Additionally, gamma rays are produced by a number of astronomical processes in which very high-energy electrons are produced, that in turn cause secondary gamma rays via bremsstrahlung, inverse Compton scattering, and synchrotron radiation.
49.
However, refined Compton experiments showed that energy momentum is conserved extraordinarily well in elementary processes; and also that the jolting of the electron and the generation of a new photon in Compton scattering obey causality to within 10 ps.

The dynamic structure factor contains all non-resonant electronic excitations, including not only the core-electron excitations observed in XRS but also e . g . plasmons, the collective fluctuations of valence electrons, and Compton scattering.
