Abstract
pi (-)pi (-)pi (-) correlations from Pb+Pb collisions at 158 GeV/c per nucl eon are presented as measured by the focusing spectrometer of the NA44 expe riment at CERN. The three-body effect is found to be stronger for Pb+Pb tha n for S+Pb. The two-dimensional three-particle correlation function is also measured and the longitudinal extension of the source is larger than the t ransverse extension.
