Abstract
The role of the reaction e+eââe+eâÏ+Ïâ in the pion form factor measurements via the radiative return method without photon tagging is studied in detail. It was shown, that for the KLOE event selection, it gives up to 1% contribution to the reaction e+eââÏ+Ïâγ(γ) for low invariant masses of the two-pion system.
