| Abstract: | On the basis of the space-time generalization of the classical current formalism,the two-pion correlation functions of identical particles for asymmetric partially coherent sources are calculated by simulating.The opaque and/or expanding sources that contribute to asymmetric sources being considered,the correlation functions are analyzed.A new type of parameterization for the two-pion correlation function is proposed to extract information of chaoticity,size,and asymmetry of the sources from experiments. |
