详细
The reliability of data of (γ, 1 ) and (γ, 2 ) reactions on 52Cr obtained in experiment on the beam of bremsstrahlung using the corrections to the neutron yield cross section σ(γ, ) = σ(γ, 1 ) + 2σ(γ, 2 ) calculated via statistical theory was investigated. Using the experimental-theoretical method for evaluation of photoneutron partial reaction cross sections based on objective physical criteria it was shown that partial reaction cross sections obtained do not satisfy physical criteria of reliability. Experimental cross section of the reaction 52Cr(γ, 1 )51Cr is unreliably significantly underestimated, but that of reaction 52Cr(γ, 2 )50Cr – on the contrary is overestimated in comparison with evaluated ones. It is shown that it is the results of the shortcomings of the method for obtaining information about cross sections of partial reactions. The main reason is the disregard of the contribution of two-nucleon reaction (γ, 1 1 ) main features (energy position and amplitude) whose cross section compete with those of also two nucleon reaction (γ, 2 ) though multiplicities of neutrons from those reactions are different.
