The cross sections for the ⁹³Nb(n,2n)^92mNb, ⁹³Nb(n,α)^90mY and the ⁹²Mo(n,p)^92mNb reactions have been measured with respect to the ¹⁹⁷Au(n,2n)¹⁹⁶Au monitor reaction at the incident neutron energy of 14.78 ± 0.19 MeV by employing methods of activation and off-line γ-ray spectrometry. The covariance analysis was carried out by taking into consideration of partial uncertainties in different attributes and correlation among the attributes. The present data have been compared with the literature data available in EXFOR, evaluated data of different libraries and theoretical values based on TALYS-1.8 code.
