Abstract
We have measured the cross section of the radiative process e+eââÏ+Ïâγ with the KLOE detector at the Frascati Ï-factory DAΦNE, from events taken at a CM energy W=1 GeV. Initial state radiation allows us to obtain the cross section for e+eââÏ+Ïâ, the pion form factor |FÏ|2 and the dipion contribution to the muon magnetic moment anomaly, ÎaμÏÏ=(478.5±2.0stat±5.0syst±4.5th)Ã10â10 in the range 0.1
