We study e(+)e(-)-> J/psi c ($) over bar by measuring the invariant mass distribution recoiling against fully reconstructed J/psi decays, using 124 fb(-1) of data collected at a center-of-mass energy of 10.6 GeV with the BABAR detector. We observe signals for eta(c)(1S), chi(c0), and eta(c)(2S) in the recoil mass distribution, thus confirming previous measurements. We measure sigma(e(+)e(-)-> J/psi+c (c) over bar )B(c (c) over bar ->> 2 charged) to be 17.6 +/- 2.8(stat)(-2.1)(+1.5)(syst) fb, 10.3 +/- 2.5(stat)(-1.8)(+1.4)(syst) fb, and 16.4 +/- 3.7(stat)(-3.0)(+2.4)(syst) fb with c (c) over bar=eta(c)(1S), chi(c0), and eta(c)(2S), respectively.
