在2.15至6.0 GeV/c的11个动量点处，π⁻-p（PI-P）的微分截面（Differential Cross Section，DCS）接近180度。实验在零梯度同步加速器（Zero Gradient Synchrotron，ZGS）上开展，采用单臂光学火花室π介子谱仪进行数据采集。
2.15、2.5和2.8 GeV/c动量点的底片（数据集1，DATA SET 1）采用手工数字化仪进行测量，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，与该数据集给出的统计误差进行了合并。
其余8个动量点对应的底片（数据集2，DATA SET 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，与该数据集给出的统计误差进行了合并。
