| contents | The photoproduction of the $^{\rm 93m}$Mo nucleus on natural molybdenum was studied using the electron beam of the LUE-40 linac RDC "Accelerator" NSC KIPT. Measurements were performed using the activation method and off-line $γ$-ray spectrometric technique. For the $^{\rm nat}$Mo($γ,x$n)$^{\rm 93m}$Mo reaction the experimental flux-averaged cross-section <$σ(E_{\rm γmax})$>$_\rm m$ at the bremsstrahlung end-point energy range of 38--93 MeV was first time determined. The theoretical values of the yields $Y_{\rm m,g}(E_{\rm γmax})$ and flux-averaged cross-sections <$σ(E_{\rm γmax})$>$_{\rm m,g}$ for the $^{\rm nat}$Mo($γ,x$n)$^{\rm 93m,g}$Mo reactions were calculated using the cross-sections $σ(E_{\rm γ})$ from the TALYS1.96 code for different gamma strength functions and level density models. The comparison showed strong discrepancies between the experimental values and the theoretical results of <$σ(E_{\rm γmax})$>$_m$. |
