Pair production - Wikipedia
https://en.wikipedia.org/wiki/Pair_production
WEBPair production is the creation of a subatomic particle and its antiparticle from a neutral boson. Examples include creating an electron and a positron, a muon and an antimuon, or a proton and an antiproton. Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus.

WEBIn addition to the photoelectric effect (photon absorption) and Compton scattering (photon scattering), there is a third process by which photons can lose energy in their interaction with matter. In this process, termed pair production, a photon can simply vanish and in its place a matter-antimatter pair of particles can appear.

WEBPair Production. Pair production occurs only for gamma-rays of high energy. By that effect the gamma-ray is transformed to matter in the form of a pair of negatively and positively charged electrons (negatron and positron).

WEBIf a photon enters matter with an energy in excess of 1.022 MeV, it may interact by a process called pair production. The photon, passing near the nucleus of an atom, is subjected to strong field effects from the nucleus and may disappear as a photon and reappear as a positive and negative electron pair.

WEBJun 16, 2023 · Pair production (PP), like the photoelectric effect, results in the complete attenuation of the incident photon. As the photon interacts with the strong electric field around the nucleus it undergoes a change of state and is transformed into two particles: one electron and one positron.

WEBRadiation - Pair Production, Photons, Electrons: Pair production is a process in which a gamma ray of sufficient energy is converted into an electron and a positron. A fundamental law of mechanics, given by Newton, is that in any process total linear (as well as angular) momentum remains unchanged.

WEBMar 26, 2023 · Pair production is a phenomenon of quantum mechanics that occurs when a high-energy photon interacts with a nucleus, creating a particle-antiparticle pair. This process is governed by Einstein’s famous equation E=mc², which states that energy and mass are interchangeable.
