The diffractive photoproduction of J/í mesons is measured with the H1 detector at the ep collider HERA using an integrated luminosity of 78pb -1 . The measurements are compared with perturbative QCD models based on BFKL and DGLAP evolution.The data are found to be compatible with s-channel helicity conservation.
