N2 - The neutron capture cross sections of (Formula presented.) and (Formula presented.) 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 (Formula presented.) and (Formula presented.) were also obtained, and 43 and 10 prompt gamma-ray peaks from (Formula presented.) ((Formula presented.)) and (Formula presented.) ((Formula presented.)) reactions were newly observed, respectively.
