Outline of Final Research Achievements

Neutron capture cross sections for xenon and krypton isotopes with high accuracy are required for FFDL method, which detects damege of fuel of fast breeding reactors. The purpose of this study were to upgrade nulcear data evaluation and design experimental technique for neutron capture cross sections for xenon and krypton isotopes below 0.1 MeV region, which there is no experimenal data. Many parameters of coupled channel optical model and exciton one in the CCONE code were optimized. Noble gas sample cases were designed in the view of decrese of background radiation in measurement of gamma-rays from neutron capture reaction.
