description: Isolated photons with high transverse energy have been studied in deep inelastic $ep$ scattering with the ZEUS detector at HERA, using an integrated luminosity of 326 pb$^{−1}$ in the range of exchanged-photon virtuality 10−350 GeV$^2$. Outgoing isolated photons with transverse energy 4 $E^{γ}_{T}$ &lt; 15 GeV and pseudorapidity −0.7 &lt; $η^γ$ &lt; 0.9 were measured with accompanying jets having transverse energy and pseudorapidity 2.5 $E^{jet}_{T}$ &lt; 35 GeV and −1.5 &lt; $η^{jet}$ &lt; 1.8, respectively. Differential cross sections are presented for the following variables: the fraction of the incoming photon energy and momentum that is transferred to the outgoing photon and the leading jet; the fraction of the incoming proton energy transferred to the photon and leading jet; the differences in azimuthal angle and pseudorapidity between the outgoing photon and the leading jet and between the outgoing photon and the scattered electron. Comparisons are made with theoretical predictions: a leading-logarithm Monte Carlo simulation, a next-to-leading-order QCD prediction, and a prediction using the $k_T$-factorisation approach
