As a research project of the Nuclear Systems Research and Development Project, we have started a study on " Improvement of the accuracy of neutron-induced fission reaction data for MAs," and are proceeding with the measurement of fission cross sections in the resonance region by introducing a neutron detector into ANNRI at J-PARC. Currently, provisional measurement data for Am-241 and Cm-245 have been obtained. In this presentation we will report the results of test analyses with the resonance analysis code AMUR. In addition, we will report the results of Monte Carlo simulations to estimate the effect of differences in fission spectra depending on the nuclide on the detection efficiency.
