    "abstract": "Preliminary experimental data for particle number ratios in the collisions of\nAu+Au at the BNL AGS (11$A$ GeV/$c$) and Pb+Pb at the CERN SPS (160$A$ GeV/$c$)\nare analyzed in a thermodynamically consistent hadron gas model with excluded\nvolume. Large values of temperature, T=140--185 MeV, and baryonic chemical\npotential, $\\mu_b=590$--270 MeV, close to the boundary of the quark-gluon\nplasma phase are found from fitting the data. This seems to indicate that the\nenergy density at the chemical freezeout is tremendous which would be indeed\nthe case for the point-like hadrons. However, a self-consistent treatment of\nthe van der Waals excluded volume reveals much smaller energy densities which\nare very far below a lowest limit estimate of the quark-gluon plasma energy\ndensity.",
