Abstract
The values of the cross section for e+e- → hadrons were reported. The measurements were performed for 85 center-of-mass energies between 2 and 5 GeV with the upgraded Beijing Spectrometer (BESII) at the Beijing Electron-Positron collider. The values obtained from BESII had an average uncertainty of about 6.6% which represented a factor of 2 to 3 improvement in precision in the 2 to 5 GeV energy region.
