Measurement of 67Zn(n,p) 67Cu, 64Zn(n,2n) 63Zn, 89Y(n,&gamma,) 90mY and 89Y(n,2n) 88Y Reaction Cross Sections at the Neutron Energy of 14.54 MeV with Covariance Analysis

The 67Zn(n,p)67Cu, 64Zn(n,2n)63Zn, 89Y(n,&gamma,)90mY and 89Y(n,2n)88Y reaction cross sections relative to the 197Au(n,2n)196Au monitor reaction have been determined at the neutron energy of 14.54 ,± ,0.002 MeV by using the method of activation and off-line &gamma,-ray spectrometry. The neutron energy used was obtained from the 3H(d,n)4He reaction. The covariance analysis was performed by taking the uncertainties arising in various attributes and the correlations between those attributes. The analyzed results from the present measurement were compared with the literature data and evaluated data of various libraries like ENDF/B-VIII, JEFF-3.3, JENDL-4.0 and ROSFOND-2010 libraries as well as with the calculated values based on TALYS-1.9 code
