【摘要】 采用伴随α粒子符合方法测量了水、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分比在10%内相符。
【Abstract】 The basic principle of associated alpha particle technique and the measurement system were introduced. The characteristic prompt gamma-rays coming from water,graphite,liquid nitrogen,ammonium nitrate,melamine and simulated samples induced by D-T neutron from generator were gained by single alpha particle 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%。
【Key words】 D-T neutron source; associated alpha particles technique; prompt gamma-rays;
