摘要：

The cross section of the process e(+)e(-)-->pi(+)pi(-)pi(0) was measured in the Spherical Neutral Detector (SND) experiment at the VEPP-2M collider in the energy region roots below 980 MeV. This measurement was based on about 1.2x10(6) selected events. The obtained cross section was analyzed together with the SND and DM2 data in the energy region roots up to 2 GeV. The omega-meson parameters m(omega)=782.79+/-0.08+/-0.09 MeV, Gamma(omega)=8.68+/-0.04+/-0.15 MeV, and sigma(omega-->3pi)=1615+/-9+/-57 nb were obtained. It was found that the experimental data cannot be described by a sum of only omega, phi, omega('), and omega(') resonance contributions. This can be interpreted as a manifestation of rho-->3pi decay, suppressed by G parity, with a relative probability B(rho-->3pi)=(1.01(-0.36)(+0.54)+/-0.034)x10(-4).
