Abstract：
We present a precise BABAR measurement on the cross section of the process e⁺e^－→π⁺π^－(γ) from threshold to an energy of 3 GeV with the initial state radiation (ISR) technique, using 232 fb^－1 of data collected with the BABAR detector at e⁺e^－ center-of-mass energies near 10.58 GeV. The ISR luminosity is determined from a study of the leptonic process e+e－→μ+μ－γ(γ). The leading-order hadronic contribution to the muon magnetic anomaly calculated using the
ππ cross section measured from threshold to 1.8GeV is (514.1±2.2(stat)±3.1(syst))×10^－10.
