Using the electron-positron storage ring VEPP-2 multipionic events have been observed at a total energy of 1.18-1.34 GeV. The experimental cross-section appears to be considerably larger than calculated within the framework of the vector dominance model for the processes e+e- → ρ{variant}π, ρ{variant}ε{lunate}, ωπ, A1π. The data on the total cross-section obtained in the framework of the statistical model with 4 pions are presented. © 1972.
