Abstract
Analyzing the mi-spectrum and two-particle correlations of negative hadrons from 158 AGeV/c Pb+Pb collisions at slightly forward rapidities we find a (thermal) freeze-out temperature of about 100 MeV and transverse flow with (v) over bar(perpendicular to) approximate to 0.55c. The M-perpendicular to -dependence of the correlation radii prefers a box-like transverse density profile over a Gaussian. From an analysis of the pion phase-space density w e find mu(pi), approximate to 60 MeV at thermal freeze-out.
