Abstract

Inclusive photon p_⊥ spectra were measured with 200 GeV/u proton,¹⁶O and³²S beams on W and Pt targets, using a conversion method. The measurement of charged pions in the same apparatus allows a comparison of the γ data with the expected γ's from hadronic decays π⁰, η, η^', ω). In all data sets, no deviation from the expected shape is observed in the range of 0.1<p_⊥<1.5 GeV/c. The number of photons normalized to pions agrees within the statistical (4%-11%) and systematical (9%) errors with the number of photons expected from hadronic decays in the integrated ranges ranges of p_⊥>0.1 GeV/c and p_⊥>0.6 GeV/c.
