Abstract

In order to describe dissipative heavy ion collisions microscopically a generalized master equation for the reduced density operator of the relative motion is derived. In the approach phase the description of the time development of the internal system is considerably simplified by employing a doorway concept. Concerning the coupling between doorway and more complex states a strong and weak coupling limit is defined. The resulting classical equation for the relative motion shows up to be reversible at the beginning of the collision process and becomes irreversible later on. The corresponding friction coefficient tourns out to be proportional to the width of the doorway states.
