The authors present results on the production of direct photons, {pi}{sup 0}, {eta} mesons on nuclear targets at large transverse momenta (p{sub T}). The data are from 530 and 800 GeV/c proton beams and 515 GeV/c {pi}{sup -} beams incident upon copper and beryllium targets that span the kinematic range of 1.0 < p{sub T} {approx}< 10 GeV/c at central rapidities.
