Study of the process \(e^+e^-\to\eta\gamma\to 7\gamma\) in the energy range \(\sqrt{s}\) = 1.07 -- 2 GeV

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 V...

Description
Summary: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.
