Photoneutron reactions in the range of giant dipole resonance

摘要

The well-known significant systematic disagreements between data on partial photoneutron reaction cross sections obtained in experiments using quasimonoenergetic annihilation photons and bremsstrahlung were investigated using objective physical criteria of data reliability. It was shown that many data are not reliable because of significant systematic uncertainties of the photoneutron multiplicity sorting methods used. The experimental-theoretical method for evaluation of reliable partial reaction cross sections was proposed and many new data were obtained.
