摘要：

The data sample of 6 pb(-1) collected by Cryogenic Magnetic Detector (CMD-2) at VEPP-2M collider in the c.m. energy range 1.04-1.38 GeV have been used to measure cross section of the process e(+)e(-) -> pi(+)pi(-)pi(0) and to study its dynamics. It is shown that for description of the invariant mass spectra of pi(+)pi(-) pairs one should take into account the omega pi(0) contribution arising due to p - omega - interference.
