Monte Carlo investigation and optimization of coincidence prompt gamma-ray neutron activation analysis

Comparison of Multiple Prompt γ-Ray Analysis and Prompt γ-Ray Analysis for the Elemental Analysis of Geological and Cosmochemical Samples

“…Therefore, difficulty of quantification arises when the γ-ray intensity from the trace element of interest is not strong enough in comparison with the background γ-ray from large amounts of other elements present in the sample. In such a situation, the multiple prompt γ-ray analysis (MPGA) method can be used to reduce background level. , Since in MPGA only the γ–γ coincident events from nuclei that simultaneously emit two or more cascade prompt γ-rays in de-excitation of the nuclei within a short interval of time are collected, the background caused by a single-γ-ray-emitting nuclide can be reduced.…”
