Photoneutron Reaction Cross Sections for \({}^{{115}}\)In
New data for cross sections of partial reactions (\(\gamma,1n\)) and (\(\gamma,2n\)) were obtained using both published data for neutron yield cross section \(\sigma(\gamma,xn)=\sigma(\gamma,1n)+2\sigma(\gamma,2n)\) and total photoneutron reaction cross section \(\sigma(\gamma,sn)=\sigma(\gamma,1n)\) + \(\sigma(\gamma,2n)\) determined in experiment on the bremsstrahlung beam. The investigation of reliability of those cross sections was carried out using the experimental-theoretical method for partial reaction cross section evaluation based on physical criteria. It was found that new evaluated cross sections of the reactions \({}^{115}\)In(\(\gamma,1n\))\({}^{114}\)In and \({}^{115}\)In(\(\gamma,2n\))\({}^{113}\)In 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 \({}^{115}\)In obtained in experiment on the beam of quasi-monoenergetic annihilation photons shows that both evaluations are close.
期刊介绍:
Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
