Photodisintegration interactions
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. WebMultiple-photon dissociation (MPD; IRMPD with infrared radiation) can be achieved by applying high-power lasers, e.g. a carbon dioxide laser, or a free-electron laser, or by long …

Two distinct processes occur during beam attenuation: absorption and scattering. Absorption As the energy of the primary x-ray beam is deposited within the atoms comprising the tissue, some x-ray photons are completely absorbed.
