一种测定裂变谱中子引起的²⁴¹Am(n,γ)²⁴²Am^g,m反应截面的新方法

摘要: 针对不同评价数据给出的裂变谱中子引起的 ²⁴¹Am(n,γ)²⁴²Am^g,m反应截面存在很大差异的状况，本文提出了一种利用钚材料实验的有关数据推算²⁴¹Am(n,γ)²⁴²Am^g,m反应截面的方法，两次实验得到的结果分别为0.506×10^-24cm²(4.1%)和0.505×10^-24 cm²(4.1%)。

Abstract: The crosssection data of ²⁴¹Am(n,γ)²⁴²Am^g,m induced by fission neutrons given by different evaluated data files are very diverse. For this situation, a new method was presented to determine the cross-section of ²⁴¹Am(n,γ)²⁴²Am^g,m using the data from plutonium material experiments. The results obtained from two experiments are 0.506×10^-24cm²(4.1%)and0.505×10^-24 cm²(4.1%), respectively.
