Abstract
The cross section of the process e+e−→π+π−π0η has been measured using a data sample of 21.8pb−1 collected with the CMD-3 detector at the VEPP-2000 e+e−collider. 2769 ±95 signal events have been selected in the center-of-mass energy range 1394–2005 MeV. The production dynamics is dominated by the ω(782)ηand φ(1020)η intermediate states in the lower energy range, and by the a0(980)ρ(770) intermediate state at higher energies
