Abstract：
The effect of absorption correlation on the analyzed results of pion interferometry is studied. The way to remove this effect is discussed by using the data from VUU simulation. The data for collisions of 1.8A GeV Ar+Pb at the Bevalac streamer chamber are analyzed. The spatial parameter of the source extracted from pion interferometry is less than the true value due to the absorption correlation. The effect of absorption correlation can be eliminated by properly constructing the background.
