PIGE - Particle Induced Gamma-Ray

PIGE is a versatile technique, which complements other ion beam techniques (especially PIXE) for sample analysis and non-destructive depth profiling. It is the most common application of nuclear analysis. The PIGE method is mostly based on nuclear reactions (p, g), (p,p´g), (p, a g) induced by MeV protons, where prompt nuclear gamma-rays are produced.
