• The process e+e−→π+π−π0η is studied in the center-of-mass energy region below 2 GeV with the SND detector at the VEPP-2000 e+e− collider. The following four intermediate states contribute to this process: ωη, ϕη, a0(980)ρ, and a structureless π+π−π0η state. We measure the total e+e−→π+π−π0η cross section and the cross sections for its components: ωη, ϕη, and a sum of a0(980)ρ and the structureless state. Our results are in agreement with previous measurements and have comparable or better accuracies.
