Description

The photonuclear reactions 93Nb(γ,n)92mNb and 93Nb(γ,3n)90tNb were investigated by the γ-activation method using a bremsstrahlung beam generated from an electron linac LUE-40 RDC “Accelerator” NSC KIPT. The flux of bremsstrahlung γ-quanta was controlled using a monitor target from natural molybdenum and the 100Mo(γ,n)99Mo reaction cross-section values.
The experimental cross-sections <σ(E)>, averaged over the bremsstrahlung spec-trum in the energy interval from the reaction threshold to the end-point bremsstrahlung energies Еγmax = (36-91) MeV, were determined for the reactions 93Nb(γ,n)92mNb and 93Nb(γ,3n)90tNb. The obtained values of <σ(E)> (presented in Figures) are in reasonable agreement with the estimates calculated using computer code TALYS 1.9 and with experimental data from [1].
