【摘要】 用４ 种不同阈能的活化箔测量和比较了两种铍系统中的绝对活化反应率。铍厚分别为５．３ 和８．４ ｃｍ ，活化箔为Ｉｎ、Ｚｎ、Ａｌ和Ｃｕ。实验总误差为５ ％ ～７ ％ 。分析和比较了实验结果与用１－ＤＡＮＩＳＮ 程序和ＥＮＤＦ／Ｂ－Ⅵ库数据的计算结果，两者间的偏差均小于７ ％ 。更多还原

【Abstract】 Absolute activation reaction rates in two beryllium systems are measured and compared using four kinds of activation foils with different energy thersholds. Thicknesses of beryllium shells are 5.3 and 8.4 cm, respectively. The foils are In, Zn, Al and Cu. The experimental error is about 5 %~7 %. The experimental results are analyzed and compared with the calculation ones, and the deviation between them is less than 7 %.更多还原
