Description
The process $e^+e^-{\to}K^+K^-\eta$ has been studied in the center-of-mass energy range from 1.59 to 2.007\,GeV using the data sample of 59.5 pb$^{-1}$, collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider in 2011-2012 and 2017 years. In the production of $K^+K^-\eta$ final state we observe the contribution of $\phi(1020)\eta$ intermediate state only. The cross section of $e^+e^-{\to}\phi(1020)\eta$ process has been measured on the base of about 3473${\pm}$78 selected signal events with the systematic uncertainty of 6$\%$. From the cross section approximation the $\phi(1680)$ meson parameters have been determined.
