摘要: Abstract The pion form factor is measured in the reaction e+e− → π+π− for center of mass energies range 480–1100 MeV. Our results are first analysed terms conventional Vector Meson Dominance formalism, and then taking into account ωπ inelastic channel. result this later formalism a (Fπ) which fits quite well all existing data on Fπ both timelike spacelike regions, mean square radius 〈rπ2〉 = 0.460 ± 0.011 fm2 or 〈r π 2 〉 1 0.678 0.008 fm .
