An optical potential abrasion-ablation collision model is used to calculate hadronic dissociation cross sections for one, two, and three nucleon removal for the first time for a 14.6A GeV 28Si beam fragmenting in aluminum, tin, and lead targets. These estimates are compared with recent semi-inclusive measurements. Significant differences between some calculated and measured semi-inclusive cross sections exist which cannot be resolved without measurements of the exclusive channel hadronic cross sections. Calculations for each exclusive reaction channel contributing to the semi-inclusive cross sections are presented and discussed.
首次使用光学势磨损-烧蚀碰撞模型来计算14.6A GeV的28Si束在铝、锡和铅靶中碎裂时一个、两个和三个核子移除的强子解离截面。将这些估计值与最近的半包容测量结果进行了比较。在一些计算得到的和测量得到的半包容截面之间存在显著差异，如果不测量专属通道的强子截面，这些差异就无法解决。文中给出并讨论了对半包容截面有贡献的每个专属反应通道的计算结果。
