Abstract
Information on dissipation in the entrance channel of heavy-ion collisions is extracted by the macroscopic reduction procedure of time-dependent Hartree-Fock theory. The method gives access to a fully microscopic description of the friction coefficient associated with the transfer of energy from the relative motion toward intrinsic degrees of freedom. The reduced friction coefficient exhibits a universal behavior, i.e., almost independent of systems investigated, whose order of magnitude is comparable with the calculations based on linear response theory. Similarly to nucleus-nucleus potential, especially close to the Coulomb barrier, there are sizable dynamical effects on the magnitude and form factor of the friction coefficient.
