We have studied the process e+e -\u2192\u3bc+\u3bc-\u3b3 at a center-of-mass energy near the \u3b3(4S) resonance for a \u3bc+\u3bc- invariant mass range near the J/\u3a8 mass and measured the cross section \u3c3(e+e-\u2192J/\u3a8 \u3b3t \u2192\u3bc +\u3bc-\u3b3). The data set, corresponding to an integrated luminosity of 88.4 fb-1, was collected using the BABAR detector at the SLAC PEP-II collider. From the measured cross section we extract the product \u393(J/\u3a8\u2192e+e-)B(J/ \u3a8\u2192\u3bc+\u3bc-) = 0.330\ub10.008\ub10.007 keV. Using the world averages for B(J/\u3a8 \u2192\u3bc+\u3bc - and B(J/\u3a8\u2192e+e-), we derive the J/\u3a8 electronic and total widths: \u393(J/\u3a8\u2192e+e -) = 5.61 \ub10.20 keV and \u393 = 94.7 \ub1 4.4 ...
