Particle Induced Gamma-ray Emission

Jump to: navigation, search


Belonging to the group of Ion beam Analysis, Particle Induced Gamma-ray Emission (PIGE) is a non-destructive analysis method, isotopically sensitive, with excellent mass resolution, which is mostly used for light elements analysis such as H, D, Li, B, C, O and F. Accelerated charged particles with a suitable (high) energy excite the target nucleus and form a compound nucleus. The compound nucleus subsequently decays and from the detection and sprectrometry of the characteristic emitted prompt gamma rays, an absolute impurity concentration can be determined.
