Abstract

Nucleus-nucleus collisions are simply regarded as sum of nucleon-nucleon collisions. Particle sources produced by nucleon\|nucleon collisions are treated as classical current. For the classical current formalism ensemble of space-time function there are two terms in two identical particle Bose-Einstein correlation function when sources are partially coherent and one is called coherent term, the other is chaotic one. According to Monte Carlo simulating theory, the algorithm for calculating correlation function of partially coherent sources is derived by generalizing chaotic one. The correlation function of partially coherent sources is simulated by this method at out and side direction of relative momentum, and the out radius of sources from the fitted result is approximately equal to the side one within the error range
