Abstract
The majority of partial and total photoneutron cross-section data were obtained using beams of quasimonoenergetic photons produced by annihilation in the flight of fast positrons and the method of neutron multiplicity-sorting procedures at Lawrence Livermore National Laboratory (California) and Saclay (France). Significant systematic disagreements between the two sets of data were obtained by employing the new objective physical data reliability criteria. It was found that many reaction cross sections are not reliable. As an example, a significant systematic uncertainty of the () cross-section data measured at Livermore is presented. The () reaction cross section was obtained as erroneous, whereas the () reaction cross section was not obtained at all. The detailed discussion of this analysis is presented. The newly unmeasured before () cross section is obtained from the experimental () cross section using simple equations based on the physical criteria.
