| 摘 要： | 一、基本原理自六十年代中期以来,中子活化瞬发γ射线元素分析技术(PNAA)得到人们广泛重视。与通常的中子活化分析(NAA)技术相比,它分析的是样品中的主要成分,若用同位素中子源,还可进行实时在线连续测定及现场分析。PNAA技术是用热中子与待测元素发生中子俘获反应,处于激发态的产物核在瞬间

| Abstract: | A system for Prompt Neutron Activation Analysis (PNAA) with isotopicneutron sources is established. The fast neutrons from ~(241)Am-Be neutron sourcesare moderated by a paraffin moderator and neutron capture gamma rays spectraare measured with a Ge(Li) detector. The optimum experimental configurationare determined. Some samples are measured using the PNAA technique. |
