Study of the process $e^+e^-\toηγ\to 7γ$ in the energy range $\sqrt{s}$ = 1.07 -- 2 GeV
The $e^+e^-\toηγ$ cross section is measured in the center-of-mass energy range from 1.07 to 2.00 GeV in the decay channel $η\to 3π^0$, $π^0\toγγ$. 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.
