Massive, projectilelike fragments (PLF) from the 209Bi+136Xe reaction at Elab/A = 28MeV were measured in coincidence with lighter charged products and neutrons, detected with 4π angular coverage. Strong correlations are observed between the deflection angle of the massive fragment, on the one hand, and various experimental measures of energy dissipation, on the other hand. These correlations, as well as the observed broadening of the primary PLF atomic-number distribution with increasing energy dissipation, are strikingly reminiscent of damped reaction features that are well understood in terms of dissipative orbiting.
