A measurement of the inclusive inelastic J/ y photoproduction cross section using the ZEUS detector at HERA is described. The cross section of the reaction e+ p → e+J/ y X was determined for events with an inelasticity, z, less than 0.9, where z is the ratio of the energy of the outgoing J/ y to the energy of the incoming photon in the proton's rest frame. The measurement was performed in the photon-proton centre of mass energy range 110 < Wgp < 160 GeV using the decay channel J/ y → e+e--. The measurements compare favourably with recent NLO calculations using the colour singlet model.
