Measurement of the cross section for e^+e^- -> ppbar at center-of-mass   energies from 2.0 to 3.07 GeV
  Cross sections for e^+e^- -> ppbar have been measured at 10 center-of-mass energies from 2.0 to 3.07 GeV by the BESII experiment at the BEPC, and proton electromagnetic form factors in the time-like region have been determined.
