~(182)W(n,n′α)~(178)Hf~(m2)反应截面研究

Analysis of the Cross Section for ~(182)W(n,n′α) ~(178)Hf~(m2) Reaction

摘要: 对当前有关182 W (n, n′α) 178Hfm2 反应截面的实验测量值和理论计算值相差 10 0倍这一分歧进行了样品成分活化分析和仔细的理论分析。所得结果排除了实验所用样品存在Hf杂质影响这一推论。理论和实验值的分歧依然存在, 可能原因是现有的理论计算程序还不能对高角动量激发态进行很好的理论预言

Abstract: The cross section for 182 W(n,n′α) 178 Hf m2 reaction is analyzed by activation analysis of the W sample and theoretical calculation.The results obtained presently show that the discrepancies between measurements and A.V.Ignatyuk’s calculation are still existed, and not caused by the Hf impurities in W sample.
