摘要

A photon momentum dependence is brought into photon-vector meson coupling strengths by taking account of the contribution of intermediate quark-antiquark state. The data on cross sections for photoproductions and leptonic widths of vector mesons, cross sections for PSI-production by off-shell photons and the pion form factor can be reproduced simultaneously by using the coupling strengths with the photon momentum dependence.
