Particle-induced Gamma ray emission

Acronyms PIGE or PIGME (particle induced gamma ray emission) 

PIGE or PIGME is a versatile non-destructive technique which is complementary to other ion beam techniques (especially particle induced X-ray emission, PIXE). It is the most common application of nuclear analysis. 

The high-energy proton beam from an accelerator is used to irradiate the sample. PIGE is mostly based on the nuclear reaction induced by MeV protons where nuclear y-rays are produced. 

The energy scale, including non-Hnearity, can be calibrated using radioactive sources. 

PIGE has similar requirements as PIXE, but the y-ray absorption in the sample is

Particle-induced gamma-ray emission (PIGE) in which nuclei are excited and gamma-rays are generated by the ion beam. 

Megaelectron volt (MeV) ion beam techniques offer a number of non-destructive analysis methods that allow to measure depth profiles of elemental concentrations in material surfaces. Elements are identified by elastic scattering, by specific nuclear reaction products or by emission of characteristic X-rays. With nuclear microprobes raster images of the material composition at the surface can be obtained. Particle-induced gamma-ray emission (PIGE) is especially suited for fluorine detection down to the ppm concentration level. 

IPM can be used simultaneously with RBS (Rutherford backscattering spectrometry), NRA (nuclear reaction analysis), PIXE (particle induced X-ray emission) or PIGE (particle induced gamma ray emission). More specialized examples include the field ion microscope (FIM), which gives better then atomic resolution in the study of high melting point materials.
