During the 2004 campaign, the n lowbar TOF collaboration measured neutron fission cross sections for {sup 233}U, {sup 241,243}Am, {sup 245}Cm, as well as the fission standards {sup 235,238}U, using a sealed Fission Ionization Chamber (FIC). The setup included a total of 16 targets and 18 electrodes mounted together in a 50-cm length chamber, allowing the measurements of all isotopes at the same time, thus in the same experimental conditions. A brief description of the facility and of the detector setup will be presented followed by the preliminary results of the analysis of {sup 235}U, {sup 233}U, and {sup 245}Cm from thermal energies up to some tenths of MeV.
