Pair 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.

Mar 26, 2023 · What is Pair Production? 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.
In this process, termed pair production, a photon can simply vanish and in its place a matter-antimatter pair of particles can appear. This phenomenon is a wonderful illustration of the fact that mass is not conserved, since the mass of the electron and positron can be created from the energy of the massless photon.
Apr 25, 2024 · Pair production is a fundamental process in particle physics where a particle and its antiparticle are created from a photon. This phenomenon was first predicted by physicist Erwin Schrödinger in 1934 and later experimentally confirmed by Carl David Anderson in 1932.

Jul 5, 2024 · Radiation - 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.
