Vp. Eismont et al., RELATIVE AND ABSOLUTE NEUTRON-INDUCED FISSION CROSS-SECTIONS OF PB-208, BI-209, AND U-238 IN THE INTERMEDIATE-ENERGY REGION, Physical review. C. Nuclear physics, 53(6), 1996, pp. 2911-2918
Measurements of neutron-induced fission cross sections for Pb-208, Bi-
209, and U-238 have been performed in the 70-160 MeV energy region at
the neutron beam facility at the The Svedberg Laboratory in Uppsala us
ing the Li-7(p,n) reaction as neutron source. The fission fragments we
re detected by thin-film breakdown counters. The neutron flux was meas
ured relative to the n-p scattering cross section with a proton-recoil
spectrometer. The results are compared with calculations and with ear
lier reported experimental data.
