In a joint experiment the TAPS and CERES collaborations have studied the production of the neutral mesons pi degrees; eta and omega in 450 GeV p-Be and p-Au collisions at the CERN SPS. The mesons were identified by their pi degrees --> gamma gamma, eta --> gamma gamma, and omega --> pi degrees gamma decay modes. The cross sections were measured down to very low p(T) (greater than or equal to 20 MeV/c) near mid-rapidity (3.0
