The reaction e/sup +/e/sup -/..--> pi../sup +/..pi../sup -/..pi../sup 0/ has been studied at c.m. energies from 760 to 800 MeV in the VEPP-2M storage ring. The following parameters were found for the ..omega.. resonance: M/sub ..omega../ = 782.2 +- 0.4 MeV, GAMMA/sub ..omega../ = 9.8 +- 0.9 MeV, sigma/sub max/(..omega --> pi../sup +/..pi../sup -/..pi../sup 0/) = 1.39 +- 0.10 ..mu..b, and GAMMA(..omega -->..e/sup +/e/sup -/) = 0.63 +- 0.05 keV.
