  The production of the $^{180\rm{m}}\rm{Hf}$ nuclei in the photoproton
reaction ${^{181}\rm{Ta}}(\gamma,p)$ was studied at end-point bremsstrahlung
energies $E_{\rm{\gamma max}}$ = 35-95 MeV. The experiment was performed at the
electron linear accelerator LUE-40 NSC KIPT with the use of the $\gamma$
activation and off-line $\gamma$-ray spectroscopy.
  The experimental values of the bremsstrahlung flux-averaged cross-sections
$\langle{\sigma(E_{\rm{\gamma max}})}\rangle_{\rm{m}}$ for the
${^{181}\rm{Ta}}(\gamma,p)^{180\rm{m}}\rm{Hf}$ reaction were determined, and at
$E_{\rm{\gamma max}} > 55$ MeV obtained for the first time.
  The measured values, also as the literature data, are significantly exceed
the theoretical flux-averaged cross-sections $\langle{\sigma(E_{\rm{\gamma
max}})}\rangle_{\rm{th}}$. The $\langle{\sigma(E_{\rm{\gamma
max}})}\rangle_{\rm{th}}$ values were calculated using the cross-section
$\sigma(E)$ computed with the TALYS1.95 code for six different level density
models.
  A comparative analysis of the calculated total cross-sections for the
reactions ${^{181}\rm{Ta}}(\gamma,p)^{180}\rm{Hf}$ and
${^{181}\rm{Ta}}(\gamma,n)^{180}\rm{Ta}$ was performed. It was shown that the
photoproton $(\gamma,p)$ to photoneutron $(\gamma,n)$ strength ratio is
consistent with the estimates based on the isospin selection rules and the
value from the $(e,e'p)$ experiment.
