Abstract

The excitation functions of \(^{nat}\)Mo(\(\alpha\), x)\(^{97}\)Ru and \(^{nat}\)Mo(\(\alpha\), x)\(^{103}\)Ru reactions in the energy range of 10–22 MeV are determined using the stacked foil activation technique and offline \(\gamma\)-ray spectrometry. The correction for \(\gamma\)-self attenuation is performed in the present measurement. The theoretical predictions of cross-section for \(^{nat}\)Mo(\(\alpha\), x)\(^{97}\)Ru and \(^{nat}\)Mo(\(\alpha\), x)\(^{103}\)Ru reactions are calculated by TALYS. The results of the experiment are compared with the existing cross-section data available in the EXFOR database and different level density models by TALYS code. The uncertainty propagation in the measured cross-sections and correlation matrix using covariance analysis has been studied in this work.

在铌锰合金上通过阿尔法诱导反应生成 97Ru 和 103Ru 放射性核素

使用叠箔活化技术和离线\(\γ\)-射线光谱法测定了能量范围为10-22 MeV的\(^{nat}\)Mo(\(\α\), x)\(^{97}\)Ru 和\(^{nat}\)Mo(\(\α\), x)\(^{103}\)Ru 反应的激发函数。在本次测量中对（\γ）自衰减进行了校正。TALYS 计算了 \(^{nat}\)Mo(\(α\), x)\(^{97}\)Ru 和 \(^{nat}\)Mo(\(α\), x)\(^{103}\)Ru 反应的理论预测截面。实验结果与 EXFOR 数据库中现有的截面数据以及 TALYS 代码计算的不同水平密度模型进行了比较。这项工作利用协方差分析法研究了测量截面和相关矩阵的不确定性传播。
