摘要
介绍了在北京谱仪Ψ (3770 )扫描实验中 ,利用快速重建数据 ,基于大角度 Bhabha散射事例测量各扫描能量点数据样本的积分亮度。
A method is introduced for the measurement of the integrated luminosity of the fast reconstructed data sample taken in BESⅡΨ(3770) scan experiment. By using this method, we measured the integrated luminosity of the data sample taken at every energy points.
