WebMar 11, 2024 · Photodisintegration is a physical process that occurs when gamma rays with massive energies strike an atomic nucleus and split it apart. Out of the entire electromagnetic spectrum, gamma rays are the most energetic, and also have the shortest wavelength, the size of an atomic nucleus or less. WebPhotodisintegration occurs when a high-energy photon is absorbed by an atomic nucleus. The nucleus splits to form lighter elements, releasing a neutron , proton or alpha particle …
