Abstract

The neutron-induced fission cross section of 242-Pu has been measured in the neutron energy range from 2 eV to 10 MeV relative to the 235-U(n,f) cross section. The CBNM electron linear accelerator was used as a pulsed neutron source. The neutron-induced fission events were detected with an ionization chamber with ns timing. A large amount of structure is observed in the fission cross section up to 500 keV neutron energy, with isolated class II resonances being resolved below 70 keV. The fission cross section in the threshold region as well as the structures in the subbarrier fission cross section are analyzed with a common fission barrier model.
