The photoproduction of 95 m Nb on nat Mo 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 γ max ) ⟩ m for the nat Mo ( γ , x n p ) 95 m Nb reaction at the bremsstrahlung end-point energy range of 38–93 MeV has been first time obtained. The estimated values ⟨ σ ( E γ max ) ⟩ g for the formation of 95 Nb in the ground state and total cross-sections ⟨ σ ( E γ max ) ⟩ tot for the studied reaction were determined. The theoretical values of the yields Y m,g,tot ( E γ max ) and flux-averaged cross-sections ⟨ σ ( E γ max ) ⟩ m , g , tot for the nat Mo ( γ , x n p ) 95 m , g , t o t Nb 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 γ max ) ⟩ m , g , tot values.
