The photoproduction of 95\rm mNb on \rm nat\rmMo was studied using the electron beam of the LUE-40 linac RDC "Accelerator" NSC KIPT. Measurements were performed using activation and off-line γ-ray spectrometric techniques. The experimental flux-averaged cross-section ⟨σ(E_\rmγmax)⟩_\rmm for the \rm nat\rmMo(γ,x\rm np)95\rm mNb reaction at the bremsstrahlung end-point energy range of 38--93 MeV has been first time obtained. The estimated values ⟨σ(E_\rmγmax)⟩_\rmg for the formation of 95Nb in the ground state and total cross-sections ⟨σ(E_\rmγmax)⟩_\rmtot for the studied reaction were determined. The theoretical values of the yields Y\rm m,g,tot(E_\rmγmax) and flux-averaged cross-sections ⟨σ(E_\rmγmax)⟩_\rmm,g,tot for the \rm nat\rmMo(γ,x\rm np)95\rm m,g,totNb reactions were calculated using the cross-sections σ(E) from the TALYS1.95 code for six different level density models. The comparison showed a significant excess of the experimental results over the theoretical ⟨σ(E_\rmγmax)⟩_\rmm,g,tot values.
