    "abstract": "Analyzing the m_t-spectrum and two-particle correlations of negative hadrons\nfrom 158 AGeV/c Pb+Pb collisions at slightly forward rapidities we find a\n(thermal) freeze-out temperature of about 100 MeV and transverse flow with\n\u003cv_t\u003e approximately 0.55c. The M_t-dependence of the correlation radii prefers\na box-like transverse density profile over a Gaussian. From an analysis of the\npion phase-space density we find pion chemical potential of approximately 60\nMeV at thermal freeze-out.",
