Abstract
The bremsstrahlung spectra of medium-energy electrons (30…100 МeV) were calculated in GEANT4. Cross-sections for photonuclear reactions were calculated in TALYS1.9. A convolution over the energy of the cross-sections of one- and many-particle reactions with the bremsstrahlung flux density was performed. The numerical values of the yield of 93Nb(γ,xn)93-xNb reactions, the activity of irradiated 93Nb targets, and the average reaction cross-sections were obtained. The differences of the bremsstrahlung spectra from electrons with close initial energies were calculated. The shape of the difference spectra was analyzed. The contributions of the quanta of the low-energy part of the difference spectrum and the quasi-monochromatic peak of the difference spectrum to the total activity of the targets were compared. An approach for correction of the experimental cross-sections of photo-nuclear reactions using the method of "bremsstrahlung spectra difference" was considered.
