RQMD predition of directed flow at CSR energy

摘要：

The predictions of the directed collective flow by using the relativistic quantum molecular dynamics model are presented for the heavy-ion reactions at HIRFL-CSR energies.The directive flow value as a function of the emitting nucloen rapidity in the center-of-mass system is calculated zith the azimuthal event plane method and two-particle angle correlation method,respectively.Comparing the rapidity dependence of directed flow in different freeze-out time windows,the evolution and development of the directed flow is investigated.We find that one can reliably obtain the earlier information of the emitting source at this energy by time analysis of the directed collective flow.Such an analysis is useful to the designing of the hadron detector at CSR.
