Preliminary experiments were performed at the ANNRI beamline of J-PARC to measure the neutron-induced fission cross-sections of Am and Cm via detecting the emitted prompt-fission neutrons with eight recoil-proton neutron detectors. These experiments are aimed as a proof-of-principle, with further measurement involving more than double the neutron detectors expected to be performed in the following years. In the present work, the preliminary fission cross-section results will be presented and compared to evaluated data, and the feasibility of the present study will be assessed.
