Аннотация:New data for cross sections of partial reactions (γ, 1n) and (γ, 2n) were obtained using both published data for neutron yield cross section σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n) and total photoneutron reaction cross section σ(γ, sn) = σ(γ, 1n) + σ(γ, 2n) determined in experiment on the bremsstrahlung beam. The investigation of reliability of those cross sections was carried out using the experimental-theoreticalmethod for partial reaction cross section evaluation based on physical criteria. It was found that new evaluated cross sections of the reactions 115In(γ, 1n)114In and 115In(γ, 2n)113In meeting physical criteria of reliability differ in a certain way from experimental ones. The comparison of new evaluated data with the results of analogous evaluation based on the results for partial reaction cross sections for 115In obtained in experiment on the beam of quasi-monoenergetic annihilation photons shows that bothevaluations are close.
