摘要：

The bremsstrahlung flux-averaged cross-sections(σ(E)) and the cross-sections per equivalent photon(σ(E)) were first measured for the photonuclear multichannel reactionAl(γ,x)Na at end-point bremsstrahlung gamma energies ranging from 35 MeV to 95 MeV.The experiments were performed with the beam from the NSC KIPT electron linear accelerator LUE-40 using the γ-activation technique.The bremsstrahlung quantum flux was calculated with the GEANT4.9.2 program and was also monitored via theMo(γ,n)Mo reaction.The flux-averaged cross-sections were calculated using the partial cross-section σ(E) values computed with the TALYS1.95 code for different level density models.Consideration is given to special features of calculating the cross-sections <σ(E)> and <σ(E)> for the case of the final nucleus 22 Na via several partial channels x:nα+dt+npt+2 n~3 He+n2 d+2 npd+2 p3 n.
