Abstract
A simple rescattering model is used to predict three-pion correlation funct ions in CERN SPS-energy S+Pb and Pb+Pb collisions. Gaussian pion source par ameters are extracted from these calculations as well as the three-pion pha se factor, cos phi. The three-pion phase factor is found to be close to uni ty for both systems and for all regions of rapidity and transverse momentum investigated. Comparisons are made with recent experimental results from N A44.
