Measurement of the cross section for e+e- -> ppbar at center-of-mass energies from 2.0 to 3.07 GeV

Abstract

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.
