Abstract
The rapidity distribution of thermal photons produced in Pb+Pb collisi ons at CERN-SPS energies is calculated within scaling and three-fluid hydrodynamics. It is shown that these scenarios lead to very different rapidity spectra. A measurement of the rapidity dependence of photon radiation can give cleaner insight into the reaction dynamics than pio n spectra, especially into the rapidity dependence of the temperature at early times.
