An exclusive measurement of slow, massive residues from the 197Au+86Kr reaction at E/A=35 MeV has been performed in coincidence with projectile-like fragments, neutrons, as well as light- and intermediate-mass charged products. The highly efficient (double 4π) detector setup used included the University of Rochester SuperBall neutron detector and the Washington University Microball. The observed large yield of slow, massive residues shows characteristics consistent with a production scenario similar to that of binary dissipative collisions. The residues result from the statistical decay of primary targetlike fragments, produced even in the most dissipative collisions identified in the present experiment.
