Abstract

In order to improve the data accuracy of neutron-capture cross-sections of minor actinides (MAs) and long-lived fission products (LLFPs), a new experimental instrument named “Accurate Neutron-Nucleus Reaction measurement Instrument” (ANNRI) has been constructed in the Materials and Life science experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), and measurements of neutron-capture cross-sections of MAs, LLFPs and some stable isotopes with high-intensity pulsed neutrons have been started. The analyses for 244Cm, 246Cm, 241Am and 237Np were finished; those for 129I, 107Pd, 99Tc , 93Zr and some stable isotopes are in progress. These results will give significant contributions in the field of developing innova...
