THE REST OF THE FILM (DATA SET 2) WAS AUTOMATICALLY SCANNED AND WE HAVE COMBINED A 9 PCT ANGLE DEPENDENT EFFICIENCY UNCERTAINTY WITH THE GIVEN STATISTICALERRORS AT THESE 8 MOMENTA. /// COMMENTS ON MODIFICATIONS TO LOVELACE71 COMPILATION BY KELLY -- LOVELACE71 HAS PRELIMINARY DATA (ID=ANTHON68).

在2.15 GeV/c至6.0 GeV/c的11个动量点处，π-质子相互作用的微分截面（Differential Cross Section, DCS）在180°附近具有显著特征。本实验于ZGS装置上开展，采用单臂光学火花室π介子谱仪完成数据采集。其中2.15、2.5与2.8 GeV/c动量点的胶片数据（数据集1）通过手工数字化方式进行测量，我们将5%的角度相关效率不确定度、2%的角度相关本底扣除不确定度，与该数据集给定的统计误差进行了合并处理。其余动量点的胶片数据（数据集2）采用自动扫描方式处理，我们将9%的角度相关效率不确定度，与该8个动量点给定的统计误差进行了合并。
