摘要
提出了一种在正负电子对撞机上、用大角度 Ｂｈａｂｈａ散射事例、在ψ（２Ｓ）共振能量下测量积分亮度的方法．对北京谱仪在北京正负电子对撞机上采集的ψ（２Ｓ）数据进行的初步测量表明方法是可行的．
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.
