Measurement of ⁹²Mo(n,α)⁸⁹Zr, ⁹⁷Mo(n,p)⁹⁷Nb, ¹⁴⁸Nd(n,2n)¹⁴⁷Nd and ¹⁴⁶Nd(n,p)¹⁴⁶Pr reaction cross sections at the neutron energy of 14.54 MeV with covariance analysis

The ⁹²Mo(n,α)⁸⁹Zr, ⁹⁷Mo(n,p)⁹⁷Nb, ¹⁴⁸Nd(n,2n)¹⁴⁷Nd and ¹⁴⁶Nd(n,p)¹⁴⁶Pr reaction cross sections with the neutron of energy of 14.54 ± 0.24 MeV have been measured by using the method of activation and off-line γ-ray spectrometry. The neutron was generated from the D-T reaction at the PURNIMA neutron generator of BARC. The ¹⁹⁷Au(n,2n)¹⁹⁶Au monitor reaction was used for the estimation of neutron flux. The covariance analysis for the uncertainties of the cross sections has been carried out by considering the partial uncertainties of different attributes. The present data have been compared with the literature data, evaluated data and theoretically calculated values from TALYS-1.9 code. (author)
