Abstract：
Influence of the central collective flow on a two-particle correlation function is discussed. The Monte Carlo calculation was used to describe how the single-particle and two-particle spectra from a hot emission source are affected by the central collective flow. The two-proton correlation function for the 100 MeV/u Ni+Ni system at b=0 fm was calculated using the QMD model. The particle interchange method was developed and used to prove the existence of a central collective flow in central collisions of the 100 MeV/u Ni+Ni system. The results show that the two-particle correlation functions are indeed sensitive to the central collective flow. This might provide a method to study the central collective flow formed in central collisions for medium heavy system at energies above 100 MeV/u.
