Fission Cross Sections of Uranium, Thorium, Bismuth, Lead, and Gold Induced by 58- to 100-MeV Alpha Particles

The results presented in this paper have been obtained from experiments using a makrofol (a polycarbonate) detector. After a brief description of the experimental technique, values of measured cross sections are given. These values are discussed in comparison with some known results about spallation reactions, referring to reaction cross sections theoretically calculated from optical models.
