The predictions of the model are done at the freeze-out parameters determined earlier from measured particle yields and $p_{T}$ spectra. The results agree qualitatively well with the experimental data.This is a write-up of a poster presented at the Workshop on Quark-Gluon-Plasma Thermalization, Vienna, Austria, 10-12 August 2005High Energy Physics - Phenomenologytext
