Cross-sections of photonuclear reactions on ^natMo targets at end-point bremsstrahlung energy up to E_Γmax = 100 MeV

Experiments to determine the yields and bremsstrahlung flux-averaged cross-sections ⧼σ(γ_max)⧽ of photonuclear reactions on the natural Mo targets were performed on the beam from the electron linear accelerator LUE-40 with the use of the γ-activation technique. The bremsstrahlung end-point energies were in the range γ_max = 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 ⧼σ(_γmax)⧽ for photonuclear reactions on stable Mo isotopes were computed using the σ() cross-sections from the TALYS1.95 code (for the level density model LD1). A comparison of experimental and calculated cross-sections ⧼σ(E_γmax)⧽ for reactions ⁹²Mo(γ, 2n)⁹⁰Mo and ⁹²Mo(γ, pn)⁹⁰Nb was performed. (author)
