Abstract：
The relationship between Bose-Einstein coheremt radius and source radius (orroot-mean-square radius),and their dependence on the experimental windows of rapidity and transverse momentum are studied for pion source in 160A GeV/c Pb+Pb collisions,The model pion source is Produced by generator URASiMA. The results show that the coherent radius and source radius at freeze-out not only have difference in magnitude but also in behavior.
