Abstract

Data sets were collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of √ s = 3.650 GeV during May 2009 and at √ s= 3.773 GeV from January 2010 to May 2011. By analyzing the large angle Bhabha scattering events, the integrated luminosities of the two data sets are measured %at √ s= 3.650 and 3.773 GeV to be (\rm 44.49±0.02±0.44) \rm pb^-1 and (\rm 2916.94±0.18±29.17) \rm pb^-1, respectively, where the first error is statistical and the second error is systematic.
