Abstract：
We examine the two-pion and three-pion correlation functions for a granular source model of coherent droplets under the assumption that the pions emitted from the same droplet are coherent. The chaoticity of the source increases with the number of droplets in the granular source. By comparing the normalized pure three-pion correlations of the granular source and a partially coherent Gaussian source, we find that the difference of the nomalized pure three-pion correlations between the two sources is distinct in small Q₃ regine, when the chaoticity parameter of two-pion correlation is smaller than 0.8.
