Measurement and uncertainty propagation of the (γ,n) reaction cross-section of⁵⁸Ni and⁵⁹Co at 15 MeV bremsstrahlung

Abstract

Abstract Activation cross-section of photon-induced reaction on structural materials 58 Ni and 59 Co was measured at the bremsstrahlung endpoint energy 15 MeV from an S band electron linac. The uncertainties in the (γ,n) reaction cross-section of both 58 Ni and 59 Co were estimated by using the concept of covariance analysis. The cross-section of 58 Ni(γ,n) 57 Ni reaction in the present work is slightly lower than the previous experimental data and the TENDL-2015 data. The cross-section of 59 Co(γ,n) 58 Co reaction has been measured for the first time. However, the present experimental data of 59 Co(γ,n) 58 Co reaction is very low in comparison to the TENDL-2015 and JENDL/PD-2004 data.
