Abstract

Utilizing a hydrodynamical model for the freeze-out stage in heavy-ion reactions, we extract from resolved transverse hadron spectra at midrapidity an inverse slope parameter (temperature) $T_{P b} =$ 120 MeV and an averaged transverse flow velocity $v_{⊥ P b}^{a v er} =$ 0.43 c in central collisions of Pb + Pb at 158 AGeV.
