[en] Total cross sections for reactions e⁺e^- → π⁺π^-π⁰, π⁺π^-2π⁰, 2π⁺2π^-π⁰, 2π⁺2π^-2π⁰, 3π⁺3π^- have been measured in the total c.m. energy range 1.42-2.20 GeV. Partial R = sigmasub(had)/sigmasub(μ⁺μ^-) values for two and four produced charged pions, and cross sections for positive and negative G-parity states are also reported. (orig.)
