Particle-induced gamma emission

Particle-induced gamma emission (PIGE) is a nuclear analytical technique used to study the composition of materials by analyzing the gamma rays emitted when a target material is bombarded with high-energy particles, typically protons or alpha particles. The technique is based on the principle that when the high-energy particles collide with the nuclei of the atoms in the target material, they can cause nuclear reactions that result in the emission of gamma rays.
