Аннотация: The reliability of data on (γ, 1n) and (γ, 2n) reactions on 59Co from several experiments carried out using beams of bremsstrahlung was investigated using the experimental-theoretical method of evaluation of photoneutron partial reaction cross sections based on objective physical criteria. It was found out that partial reaction cross sections obtained using the corrections to the neutron yield cross section σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n) calculated via statistical theory do not satisfy physical criteria of reliability. In experiments under discussion the (γ, 1n) reaction cross sections were significantly unreliably underestimated, but the (γ, 2n) reaction cross sections were, vice versa, overestimated. Evidently, this is because of some shortcomings of the method used for obtaining the information on partial reaction cross sections with the aid of corrections calculated via statistical theory.
