Abstract
The \(e^{+}e^{-}\to\eta\gamma\) cross section is measured in the center-of-mass energy range from 1.07 to 2.00 GeV in the decay channel \(\eta\to 3\pi^{0}\), \(\pi^{0}\to\gamma\gamma\). The data set with an integrated luminosity of 242 pb\({}^{-1}\) accumulated in the experiment with the SND detector at the VEPP-2000 \(e^{+}e^{-}\) collider is analyzed.
