Measurement of 90Zr(n,2n)89Zr and 90Zr(n,p)90mY reaction cross-sections in the neutron energy range of 10.95 to 20.02 MeV

The (n,2n) and (n,p) reaction cross-sections of 90Zr isotope have been measured in 10.95 to 20.02 MeV neutron energy range by using activation and off-line γ-ray spectrometric technique. 27Al(n,α)24Na and 115In(n,n’)115mIn monitor reactions have been used to measure the neutron fluence. The reaction cross-sections were estimated from TALYS-1.9 and EMPIRE-3.2.2 codes by making the selection of different input parameters. The uncertainties in the measurement were estimated using covariance analysis. The present results have been compared with the data measured previously by different authors and available in different evaluated nuclear data files.
