Reasonable agreement between measurements and leading order predictions.

Differential cross sections as functions of photon energy and pseudorapidity.

Abstract

Results are presented on the inclusive production of isolated prompt photons in deep inelastic scattering with a four-momentum transfer of $Q^2>4 GeV^2$. The cross sections are measured for the transverse momentum range of the photons $3 < E_T^\gamma < 10 GeV$ and for the pseudorapidity range of the photons $-1.2 < \eta^\gamma < 1.8$. They are measured differentially as a function of $E_T^\gamma$ and $\eta^\gamma$. The results are compared with the predictions of a leading order calculation, which is in reasonable agreement with the inclusive measurement.
