Abstract

Experiments to determine the yields and bremsstrahlung flux-averaged cross-sections of photonuclear reactions on the natural Mo targets were performed on the beam from the NSC KIPT electron linear accelerator LUE-40 with the use of the γ-activation technique. The bremsstrahlung end-point energies were in the range E_γmax = 35...80 MeV. The bremsstrahlung quantum flux was calculated with the program GEANT4.9.2 and, in addition, was monitored using the ¹⁰⁰Mo(γ,n)⁹⁹Mo reaction. Calculations of the yields and average cross-sections for photonuclear reactions on stable Mo isotopes were computed using the σ(E) cross-sections from the TALYS1.95 code (for the level density model LD1). A comparison of experimental and calculated cross-sections for reactions ⁹²Mo(γ,2n)⁹⁰Mo and ⁹²Mo(γ,pn)⁹⁰Nb was performed.
