Problem on Unresolved Resonance Data in ENDF/B-VI, etc

摘要

At the 2003 symposium on nuclear data it is pointed out that the self-shielding correction for the unresolved resonances of many nuclei in JENDL-3.3 is too large around the upper energy of the unresolved resonance region. It is investigated whether ENDF/B-VI, BROND-2.2 and CENDL-2.1 have the same problem for unresolved resonance data as JENDL-3.3. More than half of nuclei with unresolved resonance data in ENDF/B-VI, BROND-2.2 and CENDL-2.1 have the same problem as JENDL-3.3.
