Measurement principle in which gamma radiation emitted during the de-excitation of the compound nucleus formed by neutron capture is applied to measure the amounts of elements in a material.
Note:
The measurement method is often denoted as prompt gamma-ray neutron activation analysis (PGNAA) or prompt gamma-ray activation analysis (PGAA), though the measurement method is not in agreement with the definition of activation analysis. The term prompt gamma-ray analysis (PGA) is therefore preferred.
