Photodisintegration interactions
Webphotodisintegration, also called Phototransmutation, in physics, nuclear reaction in which the absorption of high-energy electromagnetic radiation (a gamma-ray photon) causes the … 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): 4Be + γ → 2 2He + n Antimony-124 is assembled with beryllium to make laboratory See more Photofission is a similar but distinct process, in which a nucleus, after absorbing a gamma ray, undergoes nuclear fission (splits into two fragments of nearly equal mass). See more In explosions of very large stars (250 or more solar masses), photodisintegration is a major factor in the supernova event. As the star reaches the end of its life, it reaches … See more Terrestrial lightnings produce high-speed electrons that create bursts of gamma-rays as bremsstrahlung.
