Neutron-induced ssion cross-sections of minor actinides have been measured using the n TOF white neutron source at CERN, Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear astrophysics and for the design of advanced reactor systems. The measurements at n TOF take advantage of the innovative features of the n TOF facility, namely the wide energy range, high instantaneous neutron ux and good energy resolution. Final results on the ssion cross-section of 233U, 245Cm and 243Am from thermal to 20 MeV are here reported, together with preliminary results for 241Am. The measurement have been performed with a dedicated Fast Ionization Chamber (FIC), a ssion fragment detector with a very high e ciency, relative to the very well known cross-section of 235U, measured simultaneously with the same detector.
