This award from the Academic Research infrastructure Program will help the Department of Chemistry at the University of Missouri-Columbia acquire an Automated Neutron Irradiation Nuclear Spectroscopy System which will be used in research. The research activity to be supported includes research and research training utilizing: (1) instrumental neutron activation analysis (INAA), including variations such as epithermal INAA (EINAA), cyclic INAA (CINAA) and cyclic epithermal INAA (CEINAA), (2) radiochemical neutron activation analysis (RNAA), and (3) radioisotope production. Neutron Irradiation/Nuclear Spectroscopy systems allows scientists to determine the energies of neutrons and their relative intensities by observing the gamma rays released in nuclear reactions. Activation Analysis bombards a specimen with neutrons, where identification is made by measuring the resulting ratio isotope.

这份来自学术研究基础设施项目的合同将帮助密苏里-哥伦比亚大学化学系获得一个自动中子辐照核光谱系统，该系统将用于研究。支持的研究活动包括研究和研究培训，利用：(1)仪器中子活化分析（INAA），包括超低温中子活化分析（EINAA）、循环中子活化分析（CINAA）和循环超低温中子活化分析（CEINAA）等变化，(2)放射化学中子活化分析（RNAA），以及(3)放射性同位素生产。中子辐照/核光谱学系统使科学家能够通过观察核反应中释放的伽马射线来确定中子的能量及其相对强度。活化分析用中子轰击样品，通过测量所得到的同位素比率来进行鉴定。
