Abstract: We report a measurement of the e^+e^- -> pi^+ pi^- pi^0 cross section in the energy range from 0.62 GeV to 3.5 GeV using an initial-state radiation technique. We use an e^+e^- data sample corresponding to 191 fb^-1 of integrated luminosity, collected at a centre-of-mass energy at or near the Y(4S) resonance with the BelleII detector at the SuperKEKB collider. The uncertainty at the omega and phi resonances is 2.2%. The leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment using this result is a_mu(3pi) = (48.91 +/- 0.23_stat +/- 1.07_syst) x 10^-10.
