Multigroup absorption cross sections of fission products of promethium and samarium isotopes

The capture cross sections of isotopes Pm (147, 148m, 148g, 149, 151), Sm (144, 148, 150, 152, 154, 156) have been evaluated in the energy range from 10-5 eV to 15 MeV for preparing of 80-, 21- and 26-group constants cross sections and involving them into the fission product capture cross section library for reactor calculation. The evaluation is based on the experimental data on neutron cross sections of these isotopes, reported until the middle of 1983 year, and available evaluations of other authors
