The photoproduction of 
Nb on 
was studied using the electron beam of the LUE-40 linac RDC ”Accelerator” NSC KIPT. Measurements were performed using activation and off-line 
-ray spectrometric techniques. The experimental flux-averaged cross-section 
for the 
Nb reaction at the bremsstrahlung end-point energy range of 38–93 MeV has been first time obtained. The estimated values 
for the formation of Nb in the ground state and total cross-sections 
for the studied reaction were determined. The theoretical values of the yields 
and flux-averaged cross-sections 
for the 
Nb reactions were calculated using the cross-sections 
from the TALYS1.95 code for six different level density models. The comparison showed a significant excess of the experimental results over the theoretical values.
