Photonuclear reactions ${}^{nat}$Ni($\gamma$,xn)${}^{57}$Ni and ${}^{nat}$Ni($\gamma$,xn)${}^{56}$Ni in the energy range E${}_{\gamma max}$ = 35...94 MeV

Abstract

The total bremsstrahlung flux-averaged cross-sections <$\sigma$(E${}_{\gamma max}$)> for the photonuclear reactions ${}^{nat}$Ni($\gamma$,xn)${}^{57}$Ni and ${}^{nat}$Ni($\gamma$,xn)${}^{56}$Ni have been measured in the range of end-point energies E${}_{\gamma max}$ = 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 $\gamma$-ray spectrometric technique. The calculation of the flux-average cross-sections <$\sigma$(E${}_{\gamma max}$)>${}_{th}$ was carried out using the partial cross-section values $\sigma$(E) computed with the TALYS1.95 code and bremsstrahlung $\gamma$-flux calculated by GEANT4.9.2. The experimental results are compared with theoretical calculations and data from the literature. The obtained <$\sigma$(E${}_{\gamma max}$)> values expand the energy range of previously known experimental data.
