New reliable data on the photodisintegration of 160Gd

Using objective physical reliability criteria, experimental data on the cross sections for partial photoneutron reactions on the 160Gd, obtained on the beams of quasimonoenergetic annihilation photons and methods for separation of neutron multiplicity were analyzed. It was established that the experimental cross sections of partial reactions (γ, 1n), (γ, 2n) and (γ, 3n) don’t satisfy the introduced criteria. The new data for partial and total photoneutron reactions for 160Gd cross sections were obtained using the experimental–theoretical method of evaluating the cross sections of the partial reactions, satisfying the reliability criteria. The noticeable deviations of the experimental cross sections from the evaluated once resulted from the unreliable sorting of neutrons between the channels with multiplicities were found.
