Abstract: (arXiv)

Using the upgraded Beijing Spectrometer (BESII), we have measured the total cross section for

e^+e^-

annihilation into hadronic final states at center-of-mass energies of 2.6, 3.2, 3.4, 3.55, 4.6 and 5.0 GeV. Values of

R

,

\sigma(e^+e^-\to {hadrons})/\sigma(e^+e^-\to\mu^+\mu^-)

, are determined.

electron positron: colliding beams
electron positron: annihilation
hadron: multiple production
cross section: hadronic
