    "abstract": "We investigate freeze--out in hydrodynamic models for relativistic heavy--ion\ncollisions. In particular, instantaneous freeze--out across a hypersurface of\nconstant temperature (``isothermal\u0027\u0027 freeze--out) is compared with that across\na hypersurface at constant time in the center-of-momentum frame\n(``isochronous\u0027\u0027 freeze--out). For one--dimensional (longitudinal) expansion\nthe rapidity distributions are shown to differ significantly in the two\nscenarios, while the transverse momentum spectra are remarkably similar. We\nalso investigate the rapidity distribution in greater detail and show that the\nGaussian-like shape of this distribution commonly associated with the Landau\nexpansion model in general emerges only if one neglects contributions from\ntime-like parts of the isothermal freeze--out hypersurface.",
