Pair Production

(creation of a particle/antiparticle pair)

Pair Production is the creation of a Particle and its Antiparticle from a neutral boson, such as creation of an electron and positron from a Photon near a nucleus. Pair production occurs in some astronomical phenomena and is considered potentially significant in supernovae.

The interaction between boson and whatever must have sufficient energy to provide the rest mass of the two resulting particles, which is a lot of energy, e.g., at least 1.022 MeV to produce the electron/positron pair (and much more for protons, neutrons, etc.), which is equivalent to the energy of a Gamma-Ray photon resulting from annihilation of such a pair.
