Within a hydrodynamical approach we investigate the sensitivity of singleinclusive momentum spectra of hadrons in 158A GeV Pb+Pb collisions to threedifferent equations of state of nuclear matter. Two of the equations of stateare based on lattice QCD results and include a phase transition to aquark-gluon plasma. The third equation of state has been extracted from themicroscopic transport code RQMD under the assumption of complete localthermalization. All three equations of state provide reasonable fits to datataken by the NA44 and NA49 Collaborations. The initial conditions before theevolution of the fireballs and the space-time evolution pictures differdramatically for the three equations of state when the same freeze-outtemperature is used in all calculations. However, the softest of the equationsof state results in transverse mass spectra that are too steep in the centralrapidity region. We conclude that the transverse particle momenta aredetermined by the effective softness of the equation of state during thefireball expansion.
