Description
We report preliminary results for the cross section of the $e^+e^- → \eta \gamma$ process measured in the center-of-mass energy range below 1.04 GeV. The data used for the analysis were collected by the SND detector at the VEPP-2000 $e^+e^-$ collider in 2013 and 2018 with the integrated luminosity of 82 pb$^{-1}$. Kinematic reconstruction of events was performed to select the signal process. Integrated luminosity at each energy point was measured using the process $e^+e^- → \gamma \gamma$ .
