Description
PIGE is part of nuclear reaction analysis (NRA) technique. Nuclear reactions of the incident ion with the nucleus of the target atom emit photons (gamma-rays) or charged particles. PIGE only measures the gamma-rays and is of high interest for the detection of low-Z elements. Some low-Z elements can also be detected by PIXE but the information depth is deeper for PIGE. Elemental maps can be recorded to display the distribution of elements.
