      abstract     = {The exclusive photoproduction reactions $\gamma p \to
                      J/\psi(1S) p$ and $\gamma p \to \psi(2S) p$ have been
                      measured at an $ep$ centre-of-mass energy of 318 GeV with
                      the ZEUS detector at HERA using an integrated luminosity of
                      373 pb$^{-1}$. The measurement was made in the kinematic
                      range $30 < W < 180$ GeV, $Q^2 < 1$ GeV$^2$ and $|t| < 1$
                      GeV$^2$, where $W$ is the photon--proton centre-of-mass
                      energy, $Q^2$ is the photon virtuality and $t$ is the
                      squared four-momentum transfer at the proton vertex. The
                      decay channels used were $J/\psi(1S) \to \mu^+ \mu^-$,
                      $\psi(2S) \to \mu^+ \mu^-$ and $\psi(2S) \to J/\psi(1S)
                      \pi^+ \pi^-$ with subsequent decay $J/\psi(1S) \to \mu^+
                      \mu^-$. The ratio of the production cross sections, $R =
                      \sigma_{\psi(2S)} / \sigma_{J/\psi(1S)}$, has been measured
                      as a function of $W$ and $|t|$ and compared to previous data
                      in photoproduction and deep inelastic scattering and with
                      predictions of QCD-inspired models of exclusive vector-meson
                      production, which are in reasonable agreement with the
                      data.},
