摘要
根据时空描述推广下的经典流π干涉学公式,模拟计算了不对称的部分相干源全同粒子2π关联函数,分析了"不透明"和膨胀所引起的不对称性对关联函数的影响.
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.
