The 58Ni(n,p)58Co and 58Ni(n,2n)57Ni reactions cross sections have been estimated relative to 197Au(n,2n)196Au monitor reaction at the incident neutron energy of 14.54±0.0024 MeV from the D-T fusion nuclear reaction using Purnima neutron generator carried through methods of activation and off-line γ-ray spectrometry. The uncertainty propagation and correlation for measured cross sections have been estimated using covariance analysis through considering the partial uncertainties in different attributes. The present measured reaction cross sections data have been analyzed by comparing with the literature data, with various libraries of evaluated data, like ENDF/B-VIII.0, JEFF-3.3, JENDL/AD-2017, ROSFOND-2010 and TALYS-1.9 theoretical calculations.

58Ni（n，p）58Co和58Ni（n，2n）57Ni反应在中子能量为14.54 MeV时的协方差分析

通过使用DT聚变核反应，在入射中子能量为14.54±0.0024 MeV时，相对于197Au（n，2n）196Au监测器反应，已估计了58Ni（n，p）58Co和58Ni（n，2n）57Ni反应截面Purnima中子发生器通过活化和离线γ射线光谱法进行携带。通过考虑不同属性中的部分不确定性，使用协方差分析来估计测量截面的不确定性传播和相关性。通过与文献数据以及各种评估数据库（例如ENDF / B-VIII.0，JEFF-3.3，JENDL / AD-2017，ROSFOND-2010和TALYS-1.9）进行比较，分析了当前测得的反应截面数据理论计算。
