    "abstract": "We study the different nucleus-nucleus collisions, O+Au, S+S, S+Ag, S+Au and\nPb+Pb, at the CERN-SPS energy in a one-fluid hydrodynamical approach using a\nparametrization based on baryon stopping in terms of the thickness of colliding\nnuclei. Good agreement with measured particle spectra is achieved. We deduce\nthe mass number scaling behaviour of the initial energy density. We find that\nthe equilibration time is nearly independent of the size of the colliding\nnuclei.",
