Correlation of Intermediate Energy Proton- and Neutron-Induced Fission Cross Sections in the Lead-Bismuth Region

Abstract

Neutron-and proton-induced fission cross-sections of the lead isotopes 204,[206][207][208] Tl in the intermediate energy region have been measured at the Svedberg Laboratory in Uppsala, Sweden. Average fissilities of the composite nuclei and the dependence on the nucleon energy and the parameter Z 2 /A were determined. On this basis, the correlation between the proton-and neutron-induced fission cross sections has been established in the atomic mass region A ~ 200 and for nucleon energies above 50 MeV, where shell effects do not play a very significant role. The correlation is discussed in the frame of results from calculations by the code TALYS.
