Photonuclear reactions cross-sections at energies up to 100 MeV for different experimental setups

In experiments on the electron linac LUE-40 of RDC “Accelerator” NSC KIPT, the flux-averaged cross-sections ⟨σ(Еγmax)⟩exp of photonuclear reactions ¹⁰⁰Mo(γ,n)⁹⁹Mo, ²⁷Al(γ,x)²⁴Na, ⁹³Nb(γ,n)⁹²ᵐNb, ⁹³Nb(γ,3n)⁹⁰Nb, and ¹⁸¹Ta(γ,n)¹⁸⁰ᵍTa were measured using the γ-activation technique. The theoretical flux...
