Аннотация: Experimental partial reaction cross sections for the 127I nucleus obtained independently in two laboratories were analyzed using objective physical reliability criteria. It was found that the available experimental cross sections do not satisfy these reliability criteria. The source of such discrepancies was the multiplicity neutron separation method used, based on measuring the kinetic energy of neutrons, which led to an underestimation of the reaction cross sections (γ, 1n) and to an overestimation of the reaction (γ, 2n). Also it was found that a significant portion of the neutrons from the (γ, 1n) reaction was lost in one of two experiments under discussion. Using the experimental-theoretical estimation method, new cross sections for partial and total photoneutron reactions for the 127I nucleus satisfying the physical data reliability criteria were obtained.
