A comprehensive and detailed analysis of hadronic abundances measured in $\mathrm{Au}\text{\ensuremath{-}}\mathrm{Au}$ collisions at RHIC at $\sqrt{{s}_{\mathit{NN}}}=130$ and 200 GeV is presented. The rapidity densities measured in the central rapidity region have been fitted to the statistical hadronization model and the chemical freeze-out parameters determined as a function of centrality, using …
