"There are only a very limited set of possibilities for the final state. The most probable is the creation of two or more gamma photons. Conservation of energy and linear momentum forbid the creation of only one photon. (An exception to this rule can occur for tightly bound atomic electrons. ) In the most common case, two gamma photons are created, each with energy equal to the rest energy of the electron or positron (0.511 MeV). A convenient frame of reference is that in … " - Gamma rays photons

Gamma rays photons

WebNon-linear inverse Compton scattering (NICS) is the scattering of multiple low-energy photons, given by an intense electromagnetic field, in a high-energy photon (X-ray or gamma ray) during the interaction with a charged particle, such as an electron. [11] It is also called non-linear Compton scattering and multiphoton Compton scattering. WebSo I know that X-rays are often made by the braking radiation of electrons, and since gamma rays are higher energy photons it strikes me that it should be possible to create gamma rays the same way. Though I would imagine that you would probably need heavier charged particles or significantly higher electron energies. 14 Related Topics Science
