Based on measured correlations between experimental observables in the 209 Bi 1 136 Xe reaction at E͞A 28 MeV, it is shown that multiple intermediate-mass fragment (IMF) production is a dynamical process driven by the energy of relative motion of projectilelike and targetlike fragments. This kinetic energy is converted into thermal energy of the system, until a certain "saturation" value of approximately 3 MeV͞nucleon is reached. From this point on, this "conventional" dissipation mechanism is
