The neutron capture cross section of ²⁴¹Am was measured at the ANNRI beamline of J-PARC. The time-of-flight experimental technique together with the neutron filtering system were applied to determine the cross section results for neutron energies from
10 eV to about 100 eV and at the averaged energies of 23.5, 51.5 and 127.7 keV. In the present work, alongside the cross
section data, the results of a resonance shape analysis with the REFIT code are also included.
