A measurement of the cross section for the production of an isolated photon in association with jets in proton-proton collisions at a center-of-mass energy sqrt(s) = 7 TeV is presented. Photons are reconstructed in the pseudorapidity range |eta(gamma)|25 GeV. Jets are reconstructed in the rapidity range |y(jet)|20 GeV. The differential cross section dsigma/dE_T(gamma) is measured, as a function of the photon transverse energy, for three different rapidity ranges of the leading-p_T jet: |y(jet)|
