  An alternative, to the commonly used blast-wave, model describing the
freeze-out hypersurface is applied to fit the $p_{T}$-spectra of identified
hadrons measured at relativistic heavy-ion collisions at $\sqrt{s_{NN}}=62.4,
130$ and 200 GeV. Decays of resonances are taken into account completely. It
has turned out that the fitted freeze-out temperature and baryon number
chemical potential depend weakly on the centrality of the collision and their
values are close to the chemical freeze-out values determined from fits to
particle yield ratios.
