摘要：

The folding- and azimuthal-angle and velocity distributions for the U-238 fission fragments have been measured in reactions with 100, 500, and 1000 A.MeV Pb-208. These distributions were used to decompose the fission cross section into its electromagnetic and nuclear components. The fraction of electromagnetic fission was found to be 0.16+/-0.07, 0.48+/-0.08, and 0.60+/-0.04, respectively. The electromagnetic fission cross section as a function of the Pb-208 nucleus energy is compared with theoretical predictions. The measured fission cross section from nuclear reactions (approximate to 1.5 b) is approximately constant between 100 and 1000 A.MeV.
