Abstract
A method for measuring the integrated luminosity of the e~+ e~- colliding experiment by using the wide-angle Bhabha events at the center of mass energy of the ψ(2S) resonance is presented. The determination of the integrated luminosity for the ψ(2S) data collected by the BES detector at the BEPC collider shows the feasibility of the method.
