Measurements of neutron-induced fission cross sections for 208Pb, 209Bi, and 238U have been performed in the 70–160 MeV energy region at the neutron beam facility at the The Svedberg Laboratory in Uppsala using the 7Li(p,n) reaction as neutron source. The fission fragments were detected by thin-film breakdown counters. The neutron flux was measured relative to the n-p scattering cross section with a proton-recoil spectrometer. The results are compared with calculations and with earlier reported experimental data. © 1996 The American Physical Society.
