The total bremsstrahlung flux-averaged cross-sections$\langle{\sigma(E_{\rm{\gamma max}})}\rangle$ for the photonuclear reactions$^{181}\rm{Ta}(\gamma,\textit{x}n; \textit{x} \leq 8)^{181-\textit{x}}\rm{Ta}$have been measured in the range of end-point energies $E_{\rm \gamma max}$ upto 95 MeV. The experiments were performed with the beam from the NSC KIPTelectron linear accelerator LUE-40 with the use of the activation and off-line$\gamma$-ray spectrometric technique. The calculation of average cross-sectionswas carried out using the cross-section values computed with the TALYS1.95 codefor different level density models $LD$ 1-6. A comparison between theexperimental total cross-sections $\langle{\sigma(E_{\rm{\gamma max}})}\rangle$and the theoretical values has shown satisfactory agreement for the$^{181}\rm{Ta}(\gamma,\textit{x}n)$ reactions with the escape of 1-4, 6 and 7neutrons. The closest agreement with the measured data is observed with the$LD$5 computation version, which represents the microscopic level density modeltaking into account Hilaire's combinatorial tables.
