The flux-weighted average cross-sections <σ(E)> and the isomeric yield ratios IR for the 93Nb(γ,4n)89m,gNb and 93Nb(γ,5n)88m,gNb reactions were studied. The 93Nb targets were irradiated with the bremsstrahlung beam for the end-point bremsstrahlung energies Eγmax = 36-91 MeV using the electron linac LUE-40 RDC “Accelerator” NSC KIPT. The induced γ-activities of the samples were measured using a semiconductor HPGe detector with the 20% absolute efficiency and the 1.8 keV energy resolution at the 1332 keV 60 Со γ-line.
The obtained experimental values of <σ(E)> were compared with the data from  and the theoretical values calculated using computer code TALYS1.9 (presented in figures). For the case of the 93Nb(γ,4n)89tNb reaction the theoretical results from TALYS 1.9 and found <σ(E)> are in good agreement. The comparison of the ob-tained <σ(E)> values for m- , g-states of the 93Nb(γ,5n)88m,gNb reaction and isomeric yield ratios IR with the calculations performed in TALYS 1.9 shows satisfactory agreement.
