Kurzfassung englisch:
The CERN Neutron Time-Of-Flight (n TOF) facility is well suited to measure
low cross sections as those of neutron-induced fission in subactinides. The cross
section ratios of natPb and 209Bi relative to 235U and 238U were measured using PPAC detectors
and a fragment coincidence method that allows us to identify the fission events.
The present experiment provides first results for neutron-induced fission up to 1 GeV.
Good agreement is found with previous experimental data below 200MeV. The comparison
with proton-induced fission indicates that the limiting regime where neutron-induced
and proton-induced fission reach equal cross sections is close to 1 GeV.
