摘要：

We report new measurements of inclusive direct photon production at high transverse momenta (p(T)) for pi- and p-interactions on Be at 500 Gev/c. The yields as a function Of p(T) and rapidity (y) are in good agreement with expectations from next-to-leading-log QCD calculations employing recently extracted quark and gluon structure functions.
