Energy dissipation, mass diffusion and interaction times for heavy ion collisions. [Angular momentum, nucleon diffusion coefficients, transport theory, cross sections]
Correlations of experimental observables with kinetic energy loss and fragment mass for damped heavy ion reactions are emphasized. Angular-momentum-dependent interaction times are deduced giving a time scale for the evaluation of nucleon diffusion coefficients. The energy dissipated per nucleon exchange in Kr- and Xe-induced reactions is shown to decrease with increasing kinetic energy loss. These results are compared with predictions of a one-body dissipation mechanism and microscopic transport theory for heavy ion collisions. The relative decrease of energy dissipation due to nucleon exchange with decreasing bombarding energy is a new experimental feature that is unaccounted for by the above theories.
