IAEA1399 ZZ-TH-N-CAPTURE-RI&G

1. NAME OR DESIGNATION:  ZZ-TH-N-CAPTURE-RI&G.

3. DESCRIPTION

The thermal radiative capture cross sections and resonance integrals of elements and isotopes with atomic numbers from 1 to 83 (as well as 232Th and 238U) 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 113Cd , 124Xe and 157Gd at temperatures of 150, 294 and 400K.  Comparisons have also been made of the newly evaluated capture cross sections of 6Li, 7Li, 12C and 207Pb with those determined by the k0 method.
