Abstract：
Using the dynamical transport approach RQMD with a correlation afterburner,the behavior of two-pion HBT parameters is studied for Au+Au collisions at RHIC energy s=200GeV/u. We find that the HBT size parameters do reflect the source geometry at freeze-out for both central and non-central collisions. The transverse momentum dependence of HBT size parameters is insensitive to the pressure developed during the early stage of the collisions,rather,it is sensitive to the degree of spacemomentum correlation.
