Abstract：
The effect of the multi-pion correlations on two pion interferometry in a multi-pion event is studied. A new general two-pion interferometry method is developed, taking into consideration the effect of the multi-pion correlations. The data for 1.8 A GeV Ar + Pb central collisions at the Bevalac streamer chamber are analyzed using this new method.
