We have continued our studies, reported at this conference in the previous paper1, on the interactions of heavy energetic nuclei by making a further series of runs at the LBL Bevalac. In these runs we used beams of iron, lanthanum and gold nuclei at a number of different energies interacting in targets of polyethylene, carbon, aluminum and copper. These runs will allow us to study the energy dependence of the cross-sections over the limited range of energies available at the Bevalac. Here we report on an initial analysis of the data which shows that we achieved greatly improved charge resolution over that seen before. As a result we expect to be able to make determinations of all the cross-sections needed to make comparisons with the earlier data.
