Cross sections of the Fe(n,p)Mn, Fe(n,α)Cr, Fe(n,p)Mn and Pb (n,2n)Pb reactions induced by D-T neutrons were obtained with activation method and γ-ray spectrometry technique. Experimental values measured in this work are consistent with most of the previous literature data. These reactions cross sections were theoretically calculated by using the TALYS-1.96 and EMPIRE-3.2.3 codes from threshold up to 20 MeV, and significant discrepancies were found between calculated results and experiment data. In addition, experimental values are compared with evaluated nuclear data of the CENDL-3.2, ENDF/B-VIII.0, JENDL-5, BROND-3.1 and JEFF-3.3 libraries, and significant difference was found for the Fe(n,α)Cr reaction in ENDF/B-VIII.0 library but not for other reactions.
采用活化法和γ射线能谱技术获得了D-T中子诱发的Fe(n,p)Mn、Fe(n,α)Cr、Fe(n,p)Mn和Pb(n,2n)Pb反应的截面。本工作中测量的实验值与大多数先前的文献数据一致。利用TALYS-1.96和EMPIRE-3.2.3程序从阈值到20 MeV对这些反应截面进行了理论计算，计算结果与实验数据之间存在显著差异。此外，将实验值与CENDL-3.2、ENDF/B-VIII.0、JENDL-5、BROND-3.1和JEFF-3.3库的评价核数据进行了比较，发现ENDF/B-VIII.0库中Fe(n,α)Cr反应存在显著差异，而其他反应则没有。
