A search for the production of direct photons in S+Au collisions at 200AGeV has been carried out in the CERN-WA80 experiment. For central collisions the measured photon excess at each pT, averaged over the range 0.5≤pT≤2.5GeV/c, corresponded to 5.0% of the total inclusive photon yield with a statistical error of σstat=0.8% and a systematic error of σsyst=5.8%. Upper limits on the invariant yield for direct photon production at the 90% C.L. are presented. Possible implications for the dynamics of high-energy heavy-ion collisions are discussed.
