- Аннотация: It is shown that, using published results from various experiments performed with bremsstrahlung γ-radiation beams, it is in many cases possible to obtain new data on photodisintegration of nuclei, primarily cross sections of photoneutron reactions, which were previously unknown. Such possibilities have been realized for the nuclei 52Cr and 68Zn. Previously unpublished cross sections σ(γ, 2n) and σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n) for the nucleus 52Cr, and σ(γ, 1n), σ(γ, 2n) and σ(γ, sn) = σ(γ, 1n) + σ(γ, 2n) for the nucleus 68Zn have been obtained for the first time based on published experimental data. It has been established that the experimental cross sections of partial reactions on the 52Cr nucleus do not satisfy objective physical reliability criteria. New cross sections for the reactions 52Cr(γ, 1n) and 52Cr(γ, 2n)50Cr, which meet physical criteria, have been evaluated using an experimental–theoretical method and used to determine a new cross section for the total photoneutron reaction 52Cr(γ, sn). In the case of the 68Zn nucleus, using the only published experimental cross section for neutron yield 68Zn(γ, xn), new previously unknown cross sections of partial reactions 68Zn(γ, 1n)67Zn and 68Zn(γ, 2n)66Zn, as well as the cross section of the total photoneutron reaction 68Zn(γ, sn), have been obtained for the first timeusing the experimental–theoretical method.
