Abstract

The flux-weighted average yields of the 92Mo(γ,p)91mNb, 96Mo(γ,p)95Nb, 97Mo(γ,p)96Nb, 98Mo(γ,p)97Nb, 94Zr(γ,p)93Y, 91Zr(γ,p)90mY and 92Zr(γ,p)91mY reactions were measured for the first time at an bremsstrahlung end-point energy of 20 MeV. They are equal 10,700(1600), 1920(200), 708(70), 980(100), 1067(187), 85(8) and 143(15) µb, respectively. It is shown that the semi-direct mechanism, which is taking into account the isospin splitting of the giant dipole resonance makes a much greater contribution to the mechanisms of the above reactions than the statistical one calculated using the TALYS-1.9 code.
