摘要：

We present a systematic analysis of two-pion interferometry for the central Au+Au collisions at（snn）1/2=3,5,7,11,17,27,39,62,130 and 200 GeV/c with the help of a multiphase transport（AMPT）model.Emission source-size radius parameters Rlong,Rout,Rsideand the chaotic parameter A are extracted and compared with the experimental data.Transverse momentum and aziinuthal angle dependencies of the HBT radii are also discussed for central Au+Au collisions at 200 GeV/c.The results show that the HBT radii in central collisions do not change much above 7 GeV/c.For central collisions at 200 GeV/c,the radii decrease with the increasing of transverse momentum pt but are not sensitive to the aziinuthal angle.These results provide a theoretical reference for the energy scan program of the RHIC-STAR experiment.
