摘要
From December 2011 to May 2014, about 5 fb-1of data were taken with the BESIII detector at center-ofmass energies between 3.810 Ge V and 4.600 Ge V to study the charmonium-like states and higher excited charmonium states. The time-integrated luminosity of the collected data sample is measured to a precision of 1% by analyzing events produced by the large-angle Bhabha scattering process.
