Abstrakt

During the 2004 campaign, the n_TOF collaboration measured neutron fission cross sections for

233U,

241,243Am,

245Cm,

as well as the fission standards

235,238U,

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

235U,

233U,

and

245Cm

from thermal energies up to some tenths of MeV.
