摘要：

A measurement of the inclusive cross-section for production of direct photons in ppBAR collisions at a centre of mass energy of 630 GeV is presented as a function of the photon transverse momentum. The data correspond to a total integrated luminosity of 7.4 pb-1. The results support predictions from QCD theory.
