Abstract: | A new family of simple analytic solutions of hydrodynamics is found for slowly expanding, rotationally symmetric fireballs
assuming an ideal gas equation of state. The temperature profile is position-independent only in the collisionless gas limit.
The Zimányi-Bondorf-Garpman solution and the Buda-Lund parameterization of expanding hydrodynamic particle sources are recovered
as special cases. The results are applied to predict new features of proton correlations and spectra for 1.93 AGeV Ni+Ni collisions. |
