photon dissociates into a q̄q-dipole which scatters on the nucleon and transforms into a
vector meson state. The scattering amplitude is calculated in non-perturbative QCD with the
model of the stochastic vacuum. Assuming that the physical ρ'-and ρ''-mesons are mixed
states of an active 2S-excitation and some residual hybrid state which cannot be produced
diffractively in lowest order QCD, we obtain good agreement with the data, especially the …
