New cross sections of the partial (, (, and (, 3n) and total (, Sn), and (, tot) photoneutron reactions for Pb were evaluated using the experimental-theoretical method. The evaluation procedure was based on the comparison in detail of Pb data obtained only at Livermore (USA) with Pb data obtained at Livermore, Saclay (France) and also in other experiments. It was found that in the cases of all Pb isotopes clear disagreements between Livermore data and new evaluated data can be explained by the assumption of loss of many neutrons in experimental (, 1n) reaction cross sections. It was shown that Livermore experimental data for Pb as well as for As, I, and Ta investigated before are not reliable.
