"Fission Cross-section Measurements of ²³³U, ²⁴⁵Cm and ^241,243Am at CERN n_TOF Facility";
Journal of the Korean Physical Society, 59 (2011), S. 1912 - 1915.

Neutron-induced fission 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 nTOF take advantage of the innovative features of the n_TOF facility, namely the wide energy range, high instantaneous neutron
flux and good energy resolution. Final results on the fi 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 fission fragment detector with a very high efficiency, relative to the very well known cross-section of ²³⁵U, measured simultaneously with the same detector.
