Description
The revised neutron capture cross sections for 99Tc, sup(101, 102, 104)Ru, 103Rh, 105Pd, 109Ag, and 133Cs are analyzed using experimental results obtained in recent years. For the fission products direct experimental data revised evaluations are carried out on the basis of the systematics of the radiative strength functions and the isotopical dependence of the capture cross sections. The analysis of experimental data performed and the theoretical description of cross sections with the and of the maximum likelihood method show the accuracy of the latest estimation of fission product capture cross sections in the 1 to 1000 keV neutron energy range to be 10-15%. The comparison of estimates with integral data proves the necessity of coordinating differential and integral cross sections measurements for 99Tc and 109Ag isotopes
