Measurement of Gamma_ee(J/psi), Gamma_tot(J/psi), and Gamma_ee[psi(2S)]/Gamma_ee(J/psi)

G. S. Adams, CLEO Collaboration

Using data acquired with the CLEO detector at the CESR e+e- collider at sqrt{s} = 3.773 GeV, we measure the cross section for the radiative return process e+e- --> gamma J/psi, J/p…
