Study of the process $e^+e^-toomegaetapi^0$ in the energy range $sqrt{s} <2$ GeV with the SND detector

The process $e^+e^-toomegaetapi^0$ is studied in the energy range $1.45-2.00$ GeV using data with an integrated luminosity of 33 pb$^{-1}$ accumulated by the SND detector at the $e^+e^-$ collider VEPP-2000. The $e^+e^-toomegaetapi^0$ cross section is measured for the first time. The cross section has a threshold near 1.75 GeV. Its value is about 2 nb in the energy range $1.8-2.0$ GeV. The dominant intermediate state for the process $e^+e^- to omegaetapi^0$ is found to be $omega a_0(980)$.
