Photodisintegration physics Britannica
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 • Pair-instability supernova • Silicon-burning process 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 … See more Terrestrial lightnings produce high-speed electrons that create bursts of gamma-rays as bremsstrahlung. The energy of these rays is sometimes sufficient to start photonuclear reactions resulting in emitted neutrons. One such reaction, 7N (γ,n) See more WebSchließlich wird der Photodesintegration von UHECR überschweren Kernen diskutiert.
