Description
The process $e^+e^- \to \pi^+\pi^-\pi^0\eta$ is studied at the center-of-mass
energy below 2~GeV with the SND detector at the VEPP-2000 $e^+e^-$
collider. The four intermediate states contribute to this process:
$\omega\eta$, $\phi\eta$, $a_0(980)\rho$, and a structureless
$\pi^+\pi^-\pi^0\eta$ state. We measure the total
$e^+e^- \to \pi^+\pi^-\pi^0\eta$ cross section and the cross sections for
its components: $\omega\eta$, $\phi\eta$, and a sum of $a_0(980)\rho$ and
the structureless state. Our results are in agreement with previous
measurements and have comparable or better accuracies.
