Abstract Inelastic and elasticJ/ψ (3097) photoproduction on Li6 are measured at a mean γ energy of 90 GeV in an open spectrometer. TheJ/ψ are identified by their decays intoμ + μ − ore + e −. A signal of ψ′(3685) intoμ + μ − andJ/ψπ + π − is also seen. The inelastic cross-section withZ=E ψ/Eγ〈0.9 is compared in shape and magnitude with the colour singlet model of photon-gluon fusion.
