Photodisintegration meaning
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 neutrons, protons, or an alpha particle out of the nucleus. The reactions are call… WebDec 5, 2013 · Photodisintegration Occurs at above 10 MeV A high energy photon is absorbed by the nucleus The nucleus becomes excited and becomes radioactive To become stable, the nucleus emits negatrons, protons, alpha particles, clusters of fragments, or gamma rays These high energy photons are found in radiation therapy 25. …

WebDec 20, 2024 · The underlying assumption in hard rescattering model (HRM)gdpn is that high energy photodisintegration of two-nucleon system proceeds through the two stages in which an absorption of photon by a quark of one nucleon is followed by a high-momentum transfer (hard) rescattering with a quark from the second nucleon. The latter rescattering … WebBoth pair production and photodisintegration are endothermic (energy-absorbing) processes, and, thus, tend to cause the star to collapse. However, their eventual effects on the collapsing star are different; pair production causes only a partial collapse, followed by runaway thermonuclear fusion and a supernova explosion, while ...
