摘要
研究建立了1种利用α能谱测定241Am(n,γ)242Amg,m的反应分支比K1和K2的方法。利用242Amm与242Amg半衰期差别很大的特点,分两次测量241Am辐照样品中的242Cm含量,分别推算242Amg与242Amm的生成量,从而得到K1和K2。实际分析了某反应堆辐照的样品,测得了该反应堆中子能谱对应的K1和K2值。
A method to determine the branching ratio K1 and K2 of ^241Am（n,γ）^242Am^g,m with α-spectrometry was established. Based on the fact that the half-life of ^242Am^m and ^242Am^g are quite different, the ^242Cm activity of sample irradiated in a reactor was measured at two different moments, then the production amount of ^242Am^g and ^242Am^m during irradiation was calculated, finally the K1 and K2 were obtained.
