Abstract: Isolated-photon production in photoproduction, both inclusive andtogether with a jet, has been measured with the ZEUS detector at HERAusing an integrated luminosity of $370\,\mathrm{pb}^{-1}$. Measurements were made in the isolated-photontransverse-energy and pseudorapidity ranges $6 < E_T^{\gamma} <15\,\mathrm{GeV}$ and $-0.7 < \eta^{\gamma} < 0.9$, and for jettransverse-energy and pseudorapidity ranges $4 < \ETjet <35\,\mathrm{GeV}$ and $-1.5 < \etajet < 1.8$, for exchangedphoton virtualities $Q^2 < 1.\mathrm{GeV}^2$. Differential crosssections are presented for inclusive isolated photon production asfunctions of the transverse momentum and pseudorapidity of the photon and the jet. Higher-order theoreticalcalculations are compared to the results.
