Fast neutron-induced fission at the time-of-flight facility nELBE

Kögler, T.; Beyer, R.; Junghans, A. R.; Müller, S.

The fast neutron-induced fission cross section of Pu(242) was determined the range of 0.5 MeV and in 10 MeV relative to U(235)(n,f) at the neutron time-of-flight facility nELBE. Using the high spontaneous fission rate of Pu(242) to determine the number of target atoms makes the cross section independent from the detection. Sophisticated neutron transport simulations with Geant 4 and MCNP 6 are used to correct the neutron scattering. The determined relative cross section is in good agreement with current experimental and evaluated data sets.

Keywords: neutron-induced fission cross section; neutron scattering corrections; fast neutrons; nELBE
