Abstract：
Using the dynamical transport approach RQMD, the radial collective expansion in relativistic heavy-ion collisions is studied at RHIC energy. The prediction of the radial flow is presented by analyzing the transverse mass spectra for Au+Au central collisions at the center of mass energy s=200AGeV. We conclude that the average radial flow velocity is 0.6c and the freeze-out temperature is 160MeV in Au+Au reactions.
