- Аннотация: —The reliability of experimental data on the cross sections (γ, 1n) and (γ, 2n) partial reactioncross sections measured for 58Ni nuclei in beams of bremsstrahlung gamma radiation and beams ofquasimonoenergetic annihilation photons is analyzed on the basis of objective physical criteria. It is found that the data obtained using bremsstrahlung gamma radiation do not satisfy physical criteria and areobviously unreliable. At the same time, it is shown that the reliability of the data obtained with beamsof quasimonoenergetic photons by means of photoneutron multiplicity sorting is questionable. New cross sections of partial and total photoneutron reactions on 58Ni nuclei were obtained by the experimental–theoretical evaluation method based on simultaneously employing the experimental neutron yield cross section, which is independent of the problems of experimental determination of neutron multiplicities, and the results of calculations within the combined photonuclear reaction model (CPNRM). Significant discrepancies between experimentally measured and evaluated cross sections are analyzed in detail. It is shown that the discrepancies in question are due primarily to misinterpreting a significant number of neutrons from the (γ, 1n1p) reaction as those that originate from the (γ, 2n) reaction.
