Photodisintegration

As photodisintegration is called a process in which a high-energy photon excites an atomic nucleus so that it breaks up into two or more daughter nuclei below. One can speak of a photon-induced fission. Such a photon typically has a frequency greater than 1021 Hz and thus an energy of several mega-electron volts.

Photodisintegration is a naturally occurring process. It occurs, for example in massive stars that have more than eight solar masses and have already reached the stage of Neonbrennens.
