Research Abstract

Prompt gamma-ray analysis (PGA) is a rapid, non-destructive and a analytical technique which can perform both qualitative and quantitative multi-element analysis. Gamma-ray multiplicities have been measured and used to reduce interference of gamma-ray background in PGA. The neutron capture cross sections of most nuclides exhibit strong variations (resonance) with the kinetic energy of neutron. For further improvements of the signal-to-noise ratio and sensitivity, prompt gamma-ray analysis by using resonance has been developed.
