Abstract The production of highly energetic forward neutrons has been studied in deep-inelastic scattering. The data were taken with the H1 detector at HERA in the years 2006-2007 and correspond to an integrated luminosity of 117 pb^-1. Semi-inclusive cross sections have been measured in the kinematic region 4 < Q^2 < 100 GeV^2, 0.7*10^-4 < x < 0.3*10^-1 and the fractional momentum of the neutron 0.3 < X_L < 1.0. The data are used to estimate the structure of the pion. Furthermore, the cross sections are measured differentially in neutron energy and p_T and compared to the predictions of models of leading neutron production.
