Measurement Of Zr-90(N,2n)Zr-89 And Zr-90(N,P)Y-90m 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 Zr-90 isotope have been measured in 10.95 to 20.02 MeV neutron energy range by using activation and off-line gamma-ray spectrometric technique. Al-27(n,alpha)Na-24 and In-115(n,n')In-115m 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.
