The production of protons in heavy ion collisions through the knockout mechanism (abrasion) is described using the Glauber model. The multiple knockouts from the projectile, including the inelastic collision series with the target, are considered using a closure approximation in treating energy conservation. Calculations for reactions of 12C projectiles with several targets at energies of 1 and 2A GeV arc compared to experiments. For large secondary proton momentum a strong dependence on the target mass is found and attributed to multiple scattering of the projectile knockouts.

相对论12C核碰撞中质子的正向产生。

使用Glauber模型描述了通过敲除机制（磨损）在重离子碰撞中产生的质子。在处理能量守恒时，使用闭合近似法考虑了射弹的多个击倒，包括与目标的非弹性碰撞序列。与实验相比，计算了12C弹丸在1和2A GeV能量下具有多个目标的反应。对于较大的次级质子动量，发现了对目标质量的强烈依赖性，并且归因于抛射物的基因敲除物的多次散射。
