On Neutron Activation Analysis with Gamma,Gamma Coincidence Spectrometry



Rolf L. Zeisler, Hana Cho, Ibere Souza Ribeiro Junior, Martin G. Shetty, Danyal J. Turkoglu


A new  coincidence system has been set up at NIST. It is operated with a digital data finder supported by new software developed at NIST. The system is used to explore possible enhancements in instrumental neutron activation analysis (INAA) and study applicability to neutron capture prompt gamma activation analysis (PGAA). The performance of the system is tested with certified reference materials for efficiency calibration and quantitative performance. Comparisons of INAA results based on conventional gamma-ray spectrometry data with INAA results based on coincidence data obtained from the same samples shows improvements in the counting uncertainties and demonstrates the quantitative accuracy of the new system.
