Description

The application of statistical model in heavy ion collisions is discussed in the energy range from SIS/GSI through A GS/BNL up to SPS/CERN and RHIC/BNL. It is shown that in this broad energy range hadronic yields and their ratios resemble a thermal equilibrium population along a unified freeze-out curve determined by the condition of fixed energy per particle approx. 1 GeV. The role of exact conservation of quantum numbers in the kinetic description of rarely produced particles is also analyzed. (author)
