Abstract: A precise measurement of the cross section of the process eþe ! þ ðÞ from threshold to an energy of 3 GeV is obtained with the initial state radiation (ISR) method using 232 fb 1 of data collected with the BABAR detector at eþe center-of-mass energies near 10.6 GeV. The ISR luminosity is determined from a study of the leptonic process eþe ! þ ðÞ. The leading-order hadronic contribution to the muon magnetic anomaly calculated using the cross section measured from threshold to 1.8 GeV is ð514:1 2:2ðstatÞ 3:1ðsystÞÞ 10 10.
