Excitation of ${}^{180}$Hf${}^m$ with (γ, p)-reaction

For the first time the flux-weighted average yields of ${}^{180}$Hf${}^m$ in (γ, p)-reaction were measured at the bremsstrahlung end-point energies of 20, 40 and 55 MeV, respectively by activation and off-line γ-ray spectrometric technique. The comparison of the theoretical with using of the TALYS-1.9 code and the experimental yields demonstrates the dominance of non-statistical processes. Considering of the isospin splitting for the semi-direct mechanism shows qualitative agreement of the experimental and calculated data.
