Photonuclear reactions natNi(γ,xn)57Ni and natNi(γ,xn)56Ni in the energy range Eγmax = 35-94 MeV
Abstract
The total bremsstrahlung flux-averaged cross-sections « σ (Eγmax) » for the photonuclear reactions natNi(γ , xn)57Ni and natNi(γ , xn)56Ni have been measured in the range of end-point energies Eγmax = 35-94 MeV. The experiments were performed with the beam from the NSC KIPT electron linear accelerator LUE-40 with the use of the activation and off-line γ-ray spectrometric technique. The calculation of the flux-average cross-sections « σ (Eγmax) » th was carried out using the partial cross-section values σ (E) computed with the TALYS1.95 code for the level density models LD1-6 and bremsstrahlung γ-flux calculated by GEANT4.9.2. The obtained experimental results are compared both with the theoretical calculation « σ (Eγmax) » th and with the data available in the literature. The obtained « σ (Eγmax) » values expand the energy range of previously known experimental data.
