The dependence of the $σ_T/σ_L$ ratio on the photon virtuality and on the meson wave function is analysed.6 pages, latex, 4 figures, to appear in Proc. of XV International Seminar on High Energy Physics Problems "Relativistic Nuclear Physics and Quantum Chromodynamics", Dubna September 25-29, 2000, RussiaHigh Energy Physics - Phenomenologytext
