Results obtained by measuring, in experiments at the VEPP-2M e(+)e(-) collider with the CMD-2 and SND detectors at the Novosibirsk Institute of Nuclear Physics, cross sections for e(+)e(-) -> hadronsannihilation processes at energies in the range 360 <= V root s <= 1380 MeV are surveyed. The measured cross sections and the vector-meson parameters deduced from an analysis of these cross sections The cross section for the process c(+)e(-) -> pi(+)pi(-) is compared with the spectral function for the decay Gamma(-)->pi(-)pi V-0(Gamma).
