Abstract
The inclusive single photon spectrum has been measured in the p(T) ran ge from a few MeV/c up to approximately 1 GeV/c at several rapidities in the interval from -2.1 < y(cm) < +0.5 in 18 GeV/c proton-beryllium and proton-tungsten collisions at the Brookhaven AGS. The measured pho ton distributions are compared with the expected distribution of photo ns from pi0 decays and hadronic bremsstrahlung in a search for new sou rces of ''soft'' photons at low transverse momentum.
