Abstract
An extended vector meson dominance model which includes both radial excitations of the vector mesons, and q 2 dependence of the photon-vector meson coupling is applied to radiative decays and photoproduction of the vector mesons. The parameters estimated from Ψ radiative decay, define a phenomenological prescription in which the radiative excitations play a minor role compared with the ground state vector mesons. Various predictions are made for cross sections and decay widths.
