Study of the process $e^{+}{e}^{-}\to \eta \eta \gamma$ in the energy range $\sqrt{s} = \mbox{1.17--2.00}$ GeV with the SND detector

SND Collaboration, M. N. Achasov, A. Yu. Barnyakov +35

The process $e^{+}{e}^{-}\to \eta \eta \gamma$ is studied in the center-of-mass energy range 1.17-2.00 GeV using data with an integrated luminosity of 201 pb${}^{-1}$collected by the SND detector at the…
