摘要：

Cross sections of the Al-27(n,alpha)Na-24, Zr-96(n,2n)Zr-95, In-115(n,p)Cd-115g, In-115(n, 2n)In-114m and Au-197(n,2n)Au-196/196m2 reactions induced by D-T neutrons are presented with the activation method and off-line gamma-ray spectrometry technique. Uncertainty propagation and correlation of the cross sections were estimated using covariance analysis. It shows that, our results are consistent with most of the previous literature data of EXFOR library. Experimental values, including previous literature data, are compared with evaluated nuclear data of the CENDL-3.2, BROND-3.1, ENDF/B-VIII.0, IRDFF-II, JENDL-5 and JEFF-3.3 libraries. Besides, these excitation functions were theoretically calculated by using the TALYS-2.0 code up to the neutron energy of 20 MeV. It shows that significant discrepancies were found between experiment data and those of calculated results and evaluated data.
