Abstract
Collective kinetic energy in the heavy ion collision process -especially in deep-inelastic collision process- is studied by the use of Quantum Molecular Dynamics. A new method to define the collective kinetic energy is proposed and applied to estimate the rotational and vibrational energy of fragments. The contributions of these collective motions of fragments to the energy loss are calculated to be about 20 〜 30 MeV in ^<16>O+^<93>Nb (204 MeV) reaction.
