The 92Mo(n,α)89Zr, 97Mo(n,p)97Nb, 148Nd(n,2n)147Nd and 146Nd(n,p)146Pr reaction cross sections with the neutron of energy of 14.54 ± 0.24 MeV have been measured by using the method of activation and off-line γ-ray spectrometry. The neutron was generated from the D-T reaction at the PURNIMA neutron generator of BARC. The 197Au(n,2n)196Au monitor reaction was used for the estimation of neutron flux. The covariance analysis for the uncertainties of the cross sections has been carried out by considering the partial uncertainties of different attributes. The present data have been compared with the literature data, evaluated data and theoretically calculated values from TALYS-1.9 code.

用协方差分析测量 92Mo(n,α)89Zr、97Mo(n,p)97Nb、148Nd(n,2n)147Nd 和 146Nd(n,p)146Pr 反应截面在 14.54 MeV 中子能量下

92Mo(n,α)89Zr、97Mo(n,p)97Nb、148Nd(n,2n)147Nd和146Nd(n,p)146Pr反应截面的中子能量为14.54±0.24 MeV。活化法和离线γ射线能谱法。中子是由 BARC 的 PURNIMA 中子发生器的 DT 反应产生的。197Au(n,2n)196Au 监测反应用于估计中子通量。考虑了不同属性的部分不确定性，对横截面的不确定性进行了协方差分析。目前的数据已经与文献数据、评估数据和来自 TALYS-1.9 代码的理论计算值进行了比较。
