Isolated photon production in deep inelastic ep scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 320 pb(-1). Measurements were made in the isolated-photon transverse-energy and pseudorapidity ranges 4 < E-T(gamma) < 15 GeV and 0.7 < eta(gamma) < 0.9 for exchanged photon virtualities, Q(2), in the range 10 < Q(2) < 350 GeV2 and for invariant masses of the hadronic system W-X > 5 GeV. Differential cross sections are presented for inclusive isolated photon production as functions of Q(2), x, E-T(gamma) and eta(gamma). Leading-logarithm parton-shower Monte Carlo simulations and perturbative QCD predictions give a reasonable description of the data over most of the kinematic range.
