The neutron capture cross sections of Cm-244 and Cm-246 were measured for the neutron energy range of 1-1000 eV via the neutron time-of-flight method with Accurate Neutron-Nucleus Reaction measurement Instrument (ANNRI) at Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). The world's most intense neutron pulses from the Japan Spallation Neutron Source (JSNS) enable the accurate measurement of neutron capture cross sections. Besides, single-bunched neutron pulses allow the analysis in a higher neutron energy region than the previous measurement at ANNRI. The resonance analyses were performed up to 1000 eV by using a resonance shape analysis code REFIT. The spectra of prompt gamma-rays from neutron capture reactions of Cm-244 and Cm-246 were also obtained, and 43 and 10 prompt gamma-ray peaks from Cm-244 (n, gamma) and 246Cm (n, gamma) reactions were newly observed, respectively.
