Predictions are presented for large-p/sub T/ direct photon production in p-barp collisions at CERN ISR (..sqrt..s = 63 GeV), CERN collider (540 GeV), and Fermilab Tevatron (1600 GeV) energies in perturbative QCD. Two sets of gluon and other parton distributions determined from deep-inelastic scattering are used. Higher-order corrections (K factors) are approximately taken into account. Contributions from photon bremsstrahlung graphs and the related fractions of photon events accompanied by hadrons are presented and discussed in detail.
