A new γγ 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 show improvements in the counting uncertainties and demonstrates the quantitative accuracy of the new system.
美国国家标准与技术研究院（NIST）已建立了一个新的γγ符合系统。该系统由NIST开发的新软件支持的数字数据查找器进行操作。该系统用于探索仪器中子活化分析（INAA）中可能的改进，并研究其在中子俘获瞬发γ射线活化分析（PGAA）中的适用性。使用经过认证的标准物质对系统性能进行测试，以进行效率校准和定量性能评估。将基于传统γ射线能谱数据的INAA结果与基于从相同样品获得的符合数据的INAA结果进行比较，结果表明计数不确定度有所改善，并证明了新系统的定量准确性。
