Abstract
The cross sections for the 93Nb(n,2n)92mNb and 93Nb(n,α)90mY reactions and first time for the 92Mo(n,p)92mNb reaction have been measured relative to 197Au(n,2n)196Au monitor reaction at the incident neutron energy of 14.78 MeV from the 3H(d,n)4He fusion reaction by using activation and off-line γ-ray spectrometric technique. The experiment was carried out by making use of the neutron generator constructed based on the Cockcroft-Walton voltage multiplier accelerator of Purnima at Bhabha atomic research center (BARC), Mumbai. The efficiency calibration of the HPGe detector system was done by using a 152Eu point source from their known characteristic γ-ray energies with covariance analysis. The reaction cross sections were calculated with covariance analysis by taking into consideration of partial uncertainties in various attributes and correlation between those 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.
