Abstract：
Two new methods are introduced for the first time at BES to measure the integrated luminosity from events in large angle produced by QED dimuon and two-gamma production processes. With these methods,the integrated luminosities of the 6 energy points at 2.6,3.2,3.4,3.55,4.6 and 5.0 GeV scanned for the measurement of R are determined. The measured integrated luminosities are consistent with that determined using large angle Bhabha events.
