Using an abrasion-ablation collision model, which includes contributions from frictional-spectator interactions and electromagnetic dissociation, analyses of the sensitivities of predicted fragmentation cross sections to the choice of a particular abrasion formalism are made using both geometric and optical potential abrasion models. Most cross section differences obtained using the two abrasion models are less than the present experimental uncertainties, suggesting that either abrasion model is suitable for estimating isotopic and elemental fragment distributions.
使用一种磨损-烧蚀碰撞模型，该模型包括摩擦旁观者相互作用和电磁离解的贡献，利用几何和光学势磨损模型对预测的碎裂截面灵敏度进行了分析，以确定特定磨损形式的选择。使用这两种磨损模型获得的大多数截面差异小于当前的实验不确定性，这表明任何一种磨损模型都适用于估计同位素和元素碎片分布。
