The electromagnetic form factor of the pion has been measured over the energy range 640--1400 MeV with the OLYa detector on the VEPP-2M storage ring in the reaction e/sup +/e/sup -/..--> pi../sup +/..pi../sup -/. The characteristics of the rho meson and of the rho--..omega.. interference have been found. At (s)/sup 1/2/ >1000 MeV the pion form factor cannot be described as the sum of rho and rho' (1600) mesons.
