Cross-section of the $${^\textrm{nat}\textrm{Ni}}(\gamma ,\textrm{p} x\textrm{n})^{58}\textrm{Co}$$ reaction at the bremsstrahlung end-point energy of 35–94 MeV

Abstract

Abstract The photoproduction of the $$^{58}\textrm{Co}$$ 58 Co nuclei on $${^\textrm{nat}\textrm{Ni}}$$ nat Ni was studied using the induced $$\gamma $$ γ -activity method and offline $$\gamma $$ γ -ray spectrometric technique. The experiment was performed at the electron linear accelerator LUE-40 of NSC KIPT, Ukraine. The total flux-averaged cross-section $$\langle {\sigma (E_{\gamma \textrm{max}})}\rangle $$ ⟨ σ ( E γ max ) ⟩ for the $${^\textrm{nat}\textrm{Ni}}(\gamma ,\textrm{p} x\mathrm n)^{58}\textrm{Co}$$ nat Ni ( γ , p x n ) 58 Co reaction has been measured in the range of bremsstrahlung end-point energies $$E_{\gamma \textrm{max}}$$ E γ max = 35–94 MeV. The obtained $$\langle {\sigma (E_{\gamma \textrm{max}})}\rangle $$ ⟨ σ ( E γ max ) ⟩ were compared with theoretical estimates, and with experimental data found in the literature. The theoretical values of $$\langle {\sigma (E_{\gamma \textrm{max}})}\rangle _\textrm{th}$$ ⟨ σ ( E γ max ) ⟩ th were calculated using the partial cross-sections $$\sigma (E)$$ σ ( E ) from the TALYS1.96 code for different level density models and gamma strength functions.
