We report preliminary results from exclusive measurements on the reactions Nb + Au and Fe + Au at 50 to 100 MeV/A. Correlations among target fragments, energetic light charged particles and projectile fragments have been measured. These correlations indicate that fission is the result of peripheral collisions in these systems. Collisions at intermediate impact parameters result in heavy residues which do not undergo fission. More central collisions result in intermediate mass fragments and high multiplicity of light particles. An important result of this study is that the cross sections for the major classes of products change very little over the energy range 50-100 MeV/A in the systems Nb + Au and Fe + Au. 9 refs., 12 figs.
