In the present work, the neutron capture cross section measurements were carried out using the Accurate Neutron Nucleus Reaction Measurement Instrument (ANNRI) at the Materials and Life Science Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). A high intensity pulsed neutron beam from Japan Spallation Neutron Source at the MLF using the 3 GeV proton beam was utilized. NaI(Tl) detectors of ANNRI were used for capture measurements. The time-of-flight (TOF) method was employed to determine the incident neutron energy. Two-dimensional data, TOF and pulse-height (PH), were acquired and the data were analyzed based on a PH weighting technique. Resonance parameters were derived from resonance analysis using the REFIT code.
