Abstract Results are presented on the inclusive production of isolated prompt photons in deep inelastic scattering with a four-momentum transfer of Q2 > 4 GeV2. The cross sections are measured for the transverse momentum range of the photons 3 < ETg < 10 GeV and for the pseudorapidity range of the photons -1.2 < hg < 1.8. They are measured differentially as a function of ETg and hg. The results are compared with the predictions of a new leading order calculation, which is in reasonable agreement with the inclusive measurement. Comparisons with the predictions of the event generators PYTHIA and HERWIG are also presented.
