Measurements of normalised cross sections for the production of photons and neutrons at very small angles with respect to the proton beam direction in deep-inelastic ep scattering at HERA are presented as a function of the Feynman variable xF and of the centre-of-mass energy of the virtual photon-proton system W. The data are taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 131 pb-1. The measurement is restricted to photons and neutrons in the pseudorapidity range η>7.9 and covers the range of negative four momentum transfer squared at the positron vertex 6<Q2<100 GeV2, of inelasticity 0.05<y<0.6 and of 70<W<245 GeV. To test the Feynman scaling hypothesis the W dependence of the xF dependent cross sections is investigated. Predictions of deep-inelastic scattering models and of models for hadronic interactions of high energy cosmic rays are compared to the measured cross sections.
