Definition: Pair Production |
Pair ProductionNoun1. The transformation of a gamma-ray photon into an electron and a positron when the photon passes close to an atomic nucleus. Source: WordNet 1.7.1 Copyright © 2001 by Princeton University. All rights reserved. |
| Domain | Definitions |
Aerospace | An absorption process for X-ray and gamma ray radiation in which the incident photon is annihilated in the vicinity of the nucleus of the absorbing atom, with subsequent production of an electron and positron pair.This reaction does not occur for incident radiation energies of less than 1.02 million electron volts. (references) |
Mining | The transformation of a high-energy gamma ray into a pair of particles (anelectron and a positron) during its passage through matter. (references) |
Physics | Simultaneous formation of a positive and a negative electron as a result of the interaction of a photon of sufficient energy, i. e. higher than 1. 02 MeV, with the field of an atomic nucleus or other particle. Source: European Union. (references) |
| A collision process for gamma rays with energies greater than 1022-keV (two electron masses) where an electron /positron pair is produced. A heavy nucleus must be present for pair production. For high-energy gamma rays the pair production process is proportional to Z2 and ln(gamma). (references) | |
