    "abstract": "The Quantum Molecular Dynamics Model (IQMD) is used to investigate the origin\nof the collective transverse velocity observed in heavy ion experiments. We\nfind that there are three contributions to this effect: initial-final state\ncorrelations, potential interactions and collisions. For a given nuclear\nequation of state (eos) the increase of the transverse velocity with increasing\nbeam energy is caused by the potential part. For a given beam energy the\ncollective transverse velocity is independent of the nuclear eos but the\nrelative contributions of potential and collisions differ. In view of the\nimportance of the potential interactions between the nucleons it is not evident\nthat the similarity of the radial velocities measured for fragments at beam\nenergies below 1 AGeV and that for mesons at beam energies above 2 AGeV is more\nthan accidental.",
