- Аннотация: The analysis of significant systematic disagreements between the results of various photonuclear experiments was carried out for 153Eu and 165Ho experimental data obtained using the beams of quasimonoenergetic annihilation photons and the method of photoneutron multiplicity sorting. The simple objective physical criteria of data reliability - ratios Fi = SIG(g,in)/SIG(g,xn) = SIG(g,in)/[SIG(g,1n) + 2SIG(g,2n) + …], which have values not higher than 1.00 and 0.50, correspondingly were introduced. For both nuclei it was shown that experimental data are not reliable because one can see many physically forbidden negative values of (g,1n) reaction cross sections and correlated with those (g,2n) reaction cross sections for which F2 > 0.50. The experimentally-theoretical method was used for reliable partial reaction cross section data evaluation. In this treatment only experimental data for neutron yield cross section SIGexp(g,xn), free from the neutron multiplicity sorting problems, was used for partial reaction cross section evaluation together with functions Fitheor, calculated in the frame of the combined model of photonuclear reactions. Additionally SIGexp(g,xn) data obtained using bremsstrahlung were used for analysis. Evaluations of new reliable photoneutron reaction cross section data were carried out for both nuclei for partial reactions (g,1n), (g,2n) and (g,3n) and for total photoneutron reaction (g,sn) = (g,1n) + (g,2n) + (g,3n). The noticeable disagreements between evaluated and experimental data were obtained and analyzed.
