Аннотация:Objective physical criteria of data reliability allowed us to analyze the cross sections of photoneutron partial reactions (γ, 1n) and (γ, 2n) on 52Cr and 90Zr nuclei obtained on bremsstrahlung γ-radiation beams by introducing corrections calculated on the base of statistical theory to the neutron yield cross section σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n). The reasons why the experimental data for the 90Zr nucleus fully satisfy the physical criteria, while there are serious doubts in reliability of data for 52Cr nucleus, are discussed.
