Measurement of ⁶⁷Zn(n,p)⁶⁷Cu, ⁹²Mo(n,p)^92mNb, and ⁹⁸Mo(n,γ)⁹⁹Mo reaction cross sections at incident neutron energies of En = 1.6 and 3.7 MeV

Abstract

The cross sections for the reactions ⁹²Mo(n,p)^92mNb, ⁹⁸Mo(n,γ)⁹⁹Mo, and ⁶⁷Zn(n,p)⁶⁷Cu have been measured using an activation technique and an off-line gamma counting method at neutron energies of 1.6 and 3.7 MeV. The ⁷Li(p,n)⁷Be reaction was used as the neutron source with the proton beam from the 14-MV Bhabha Atomic Research Centre-Tata Institute of Fundamental Research Pelletron accelerator. The reaction ¹¹⁵In(n,n')^115mIn was used as the standard for the cross-section measurement. The measured data were compared with the predictions of the EMPIRE-2.19 statistical model code based on the Hauser-Feshbach theory and good agreement, after some adjustment of the level density parameter, is obtained for all the systems.
