摘　　要：We calculate the HBT radius R_(S) for π^(+)with Coulomb interaction using the string melting version of a multiphase transport(AMPT)model.We study the relationship between the single-particle space-momentum angle and the particle sources and discuss HBT radii without single-particle space-momentum correlation.Additionally,we study the Coulomb interaction effect on the numerical connection between the single-particle space-momentum angle distribution and the transverse momentum dependence of R_(S).
