Abstract

We report a correlation between the kinetic energy loss and nucleon diffusion for Kr- and Xe-induced reactions on heavy targets. Although this correlation suggests that these two phenomena occur on the same general time scale, the rate of kinetic energy loss decreases with interaction time. Evidence is presented to show that the initial energy dissipation rate is consistent with a frictional force which is proportional to the relative velocity.
