On the $\sigma_L/\sigma_T$ Ratio in Polarized Vector Meson   Photoproduction
  We study the spin-dependent cross-sections of vector meson photoproduction for longitudinally and transversely polarized photons within a QCD- model. The dependence of the $\sigma_T/\sigma_L$ ratio on the photon virtuality and on the meson wave function is analysed.
