Description
Phenomenological model, which describe very well the coupling of the $\pi^0, \eta, \eta^{'}$ mesons to two photons is presented. The model of the form factors is consistent with the data in the space-like region, as well with the data in the time-like region with exception of the $\pi^0$ BaBar data and $\eta$ CMD2 data. The obtained form factors are implemented in Monte Carlo event generator Phokhara and Ekhara and investigation of the impact of radiative corrections for a cross section of $e^+ e^- \to \gamma \pi^0, (\eta, \eta^{'} )$ is studied.
