Abstract：
Particle-particle correlation functions have been measured for ⁴⁰Ar+¹⁹⁷Au collisions at E/A=25 MeV. Emission time of light particles has been extracted from correlation functions using the three-body trajectory model. The average emission time varies with the energy of particles. It decreases from about 300 fm/c for low energy particles to about 100 fm/c for energetic particles.
