【摘要】 本文介绍了伴随α粒子符合方法测量非弹γ谱的基本原理和测量系统。测量了水、石墨、液氮样品的¹⁶O、¹²C、¹⁴N核素以及硝铵、三聚氰胺、尿素和模拟样品的d-T中子作用的非弹瞬发γ谱,利用反卷积对化合物的脉冲幅度谱进行了解谱,实验获得的元素份额与其化学成份比在10%内相符。更多还原

【Abstract】 This article introduces the basic principle of associated alpha particles technique and the measurement system.The characteristic prompt gamma-rays come from water,graphite,liquid nitrogen、ammonium nitrate、melamine and simulated samples induced by D-T neutron from generator were gained by single alpha particles detector and gamma-ray detector.The complex gamma-ray spectra were deconvolved.The element ratio between the experiment and chemic molecular formula is agreement in 10%.更多还原
