    "abstract": "The present knowledge about hadrons produced in relativistic heavy ion\ncollisions is compatible with chemical freeze-out happening when the energy\ndensity divided by the particle density reaches the value of 1 GeV. This\nobservation is used to determine the energy dependence of the chemical\nfreeze-out parameters T_{ch} and mu_B^{ch} for beam energies varying between 1\nand 200 A.GeV. The consequences of this energy dependence are studied for\nvarious particle ratios. Predictions for particle ratios at beam energy 40\nA.GeV are presented. The conditions for thermal freeze-out are also determined.\nThese correspond either to an energy density of 45 MeV/fm**3 or to a particle\ndensity of 0.05/fm**3.",
