Prompt photon production has been studied in $$\bar{p}p$$ collisions at $$ \sqrt{s}$$=1.8 TeV using the CDF and DØ detectors at Fermilab. The measured inclusive isolated photon spectrum at CDF and DO/ are used to test NLO QCD predictions. The CDF result shows that additional soft radiation (K_T) in excess of NLO QCD is required to explain the data. No new resonance is observed in the photon+jet mass spectrum from DO/ which is consistent with NLO QCD predictions. The pseudorapidity distribution of the leading jet in photon events at CDF is compared to different parton distribution sets. The angular distribution is found to be better explained by a larger Bremsstrahlung contribution.
