In physics, induced gamma emission (IGE) refers to the process of fluorescent emission of gamma rays from excited nuclei, usually involving a specific nuclear isomer. It is analogous to conventional fluorescence, which is defined as the emission of a photon (unit of light) by an excited electron in an atom or molecule. In the case of IGE, nuclear isomers can store significant amounts of

Induced gamma emission Infogalactic: the planetary

Induced gamma emission is an example of interdisciplinary research bordering on both nuclear physics and quantum electronics. Viewed as a nuclear reaction it would belong to a class in which only photons were involved in creating and destroying states of nuclear excitation. It is a class usually overlooked in traditional discussions.

Particle-induced gamma emission Wikipedia

Particle-induced gamma emission (PIGE) is a form of nuclear reaction analysis, one of the ion beam analysis thin-film analytical techniques.. Typically, an MeV proton beam is directed onto a sample which may be tens of microns thick, and the fast protons may excite the target nuclei such that gamma

The induced release of the energy stored in nuclear isomers in the form of an incoherent gamma burst is of great scientific and technological importance. Powerful sources of induced gamma-ray radiation could be obtained, which would be an intermediary step to the development of a gamma-ray laser.
