The thermal radiative capture cross sections and resonance integrals of elements and isotopes with atomic numbers from 1 to 83 (as well as Th and U) have been re-evaluated by taking into consideration all known pertinent data published since 1979. This work has been undertaken as part of an IAEA co-ordinated research project on "Prompt capture gamma-ray activation analysis". Westcott g-factors for radiative capture cross sections at a temperature of 300K were computed by utilizing the INTER code and ENDF-B/VI (Release 8) library files. The temperature dependence of the Westcott g-factor is illustrated for Cd , Xe and Gd at temperatures of 150, 294 and 400K. Comparisons have also been made of the newly evaluated capture cross sections of Li, Li, C and Pb with those determined by the k0 method.
