Measurement of 115 In(n,2n) 114m In and 197 Au(n,2n) 196 Au reaction cross sections at the neutron energies of 13.52 and 14.54  MeV with covariance analysis

AbstractThe115In(n,2n)114mIn and197Au(n,2n)196Au reaction cross sections have been measured relative to the27Al(n, α)24Na monitor reaction at the two different incident neutron energies of 13.520  ± 0.005 MeV and 14.54 ± 0.24 MeV. The neutrons from the D-T fusion reaction at the Purnima neutron generator were used for activation followed by off-line γ-ray spectrometry. The uncertainty propagation and correlation of measured reaction cross sections were estimated using covariance analysis through considering the partial uncertainties in different attributes. The measured reaction cross sections from the present work have been compared with the literature data from EXFOR compilation, ENDF data of various libraries and theoretically calculated values from the TALYS-1.9 code.
