Emission Time of Light Particles with Respect to Measurement Angle

  •  Institute of Modern Physics, The Chinese Academy of Sciences, Lanzhou 730000, China

  • Particle particle correlation functions at small correlation angle have been measured for 40Ar+93Nb collision at E 25MeV/u. Based on three body trajectory calculation the emission time scale of light particles has been extracted from correlation function of two particles at small relative momentum. The mean emission time scale decreases with increasing sum of the kinetic energies of the particles in a correlated pair. It decreases from about 500 fm/c for low energy particles to about 50 fm/c for high energy particles. And the extracted emission time scales from larger detection angle are longer than that extracted from the data obtained at small detection angle, which can be explained as the more particles emitted from equilibrated system.

Abstract: Particle particle correlation functions at small correlation angle have been measured for 40Ar+93Nb collision at E 25MeV/u. Based on three body trajectory calculation the emission time scale of light particles has been extracted from correlation function of two particles at small relative momentum. The mean emission time scale decreases with increasing sum of the kinetic energies of the particles in a correlated pair. It decreases from about 500 fm/c for low energy particles to about 50 fm/c for high energy particles. And the extracted emission time scales from larger detection angle are longer than that extracted from the data obtained at small detection angle, which can be explained as the more particles emitted from equilibrated system.
