Photodisintegration (also called phototransmutation, or a photonuclear reaction) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic particle. The incoming gamma ray effectively knocks one or more … See more A photon carrying 2.22 MeV or more energy can photodisintegrate an atom of deuterium: 1D + γ → 1H + n James Chadwick and Maurice Goldhaber used this reaction to … See more A photon carrying 1.67 MeV or more energy can photodisintegrate an atom of beryllium-9 (100% of natural beryllium, its only stable isotope): See more Terrestrial lightnings produce high-speed electrons that create bursts of gamma-rays as bremsstrahlung.
