| Abstract | We study the process e(+)e(-) -> pi(+)pi(-)eta gamma, where the photon is radiated from the initial state. About 8000 fully reconstructed events of this process are selected from the BABAR data sample with an integrated luminosity of 469 fb(-1). Using the pi(+)pi(-)eta invariant mass spectrum, we measure the e(+)e(-) -> pi(+)pi(-)eta cross section in the e(+)e(-) center-of-mass energy range from 1.15 to 3.5 GeV. The cross section is well described by the Vector-Meson dominance model with four.-like states. We observe 49 +/- 9 events of the J/Psi decay to pi(+)pi(-)eta and measure the product Gamma B-J/Psi -> e+e-(J/Psi ->pi+pi-eta) = 2.34 +/- 0.43(stat) +/- 0.16(syst) eV. | ||||
