摘要

We report measurements made with the CLEO detector at the Cornell Electron Storage Ring (CESR) of the total cross section for e+e-hadrons at the (1S), (2S), and (3S), and in the nearby nonresonant continuum. We find R=3.770.06 (statistical) 0.24 (systematic) for the ratio of the nonresonant hadronic cross section to the cross section for muon-pair production at a center-of-mass total energy W=10.4 GeV. For the leptonic decay widths ee of the (1S), (2S), and (3S) we obtain 1.300.050.08, 0.520.030.04, and 0.420.040.03 keV, respectively.
