\begin{document}${^{\rm{nat}}{\rm{Mo}}}(\gamma,x{{{np}}})^{95{{m,g}}}{\rm{Nb}}$\end{document} photonuclear reaction was studied using the electron beam from the NSC KIPT linear accelerator LUE-40. The experiment was performed using the activation and off-line γ-ray spectrometric technique. The experimental isomeric yield ratio (IR) was determined for the reaction products \begin{document}$^{95{{m,g}}}{\rm{Nb}}$\end{document} at the bremsstrahlung end-point energy \begin{document}$ E_{\rm{\gamma max}} $\end{document} range of 38–93 MeV. The obtained values of IR are in satisfactory agreement with the results of other studies and extend the range of previously known data. The theoretical values of the yields \begin{document}$Y_{{{m,g}}}(E_{\rm{\gamma max}})$\end{document} and the IR for the isomeric pair \begin{document}$^{95{{m,g}}}{\rm{Nb}}$\end{document} from the \begin{document}${^{\rm{nat}}{\rm{Mo}}}(\gamma,x{{{np}}})$\end{document} reaction were calculated using the partial cross-sections \begin{document}$ \sigma(E) $\end{document} from the TALYS1.95 code for six different level density models. For the investigated range of \begin{document}$ E_{\rm{\gamma max}} $\end{document}, the theoretical dependence of IR on energy was confirmed – the IR smoothly increases with increasing energy. The comparison showed a noticeable difference (more than 3.85 times) in the experimental IR relative to all theoretical estimates."> Isomeric pair <sup>95</sup><i><sup>m,g </sup></i>Nb in the photonuclear reactions on <sup>nat</sup>Mo at the bremsstrahlung end-point energy of 38–93 MeV -
