Abstract：
With an upgraded Beijing Spectrometer (BESII) at the Beijing Electron Positron Collider (BEPC), the BES collaboration finished two runs of R scan in the energy region from 2 to 5 GeV. R values for all 6+85 scanned energy points are presented, with an average undertainty of 6.6%,which represents an improvement by a factor of 2—3. These measurements make an important contribution to the precision determination of a(M2Z), the QED coupling constant evaluated at the Z pole. The results also contribute to the interpretation of muon g－2 measurement.
