Quasi-elastic (z > 0.95) photo-production of ψ(2S) mesons has been observed at HERA for photon-proton centre-of-mass energies in the range 40 to 160 GeV. The ψ(2S) mesons were identified through their decays to l+l− and to J/ψ π+π−, where the J/ψ subsequently decays to l+l−, the lepton l being either a muon or an electron. The cross-section for quasi-elastic photoproduction was measured to be (18.0±2.8(stat)±3.0(syst)) nb at a photon-proton centre-of-mass energy of 80 GeV. The ratio of the ψ(2S) to J/ψ quasi-elastic cross-sections is (0.150 ± 0.027(stat) ± 0.022(syst)). Submitted to Physics Letters B C. Adloff35, S. Aid13, M. Anderson23, V. Andreev26, B. Andrieu29, V.
