Light ion breakup cross sections are important for studies of cosmic ray interactions in the inter-stellar medium or radiation protection considerations of energy deposition in shielding and tissues. Abrasion cross sections for heavy ion reactions have been modeled using the Glauber model in the large mass limit or Eikonal form of the optical potential model. Here we formulate an abrasion model for ⁴He fragmentation on protons using the Glauber model avoiding the large mass limit and include a model for final state interactions. Calculations of energy dependent total, absorption, elastic and breakup cross sections for ⁴He into ³He or ³H with proton targets are shown to be in good agreement with experiments for energies from 100 to 100,000 MeV/u. The Glauber model for light nuclei with and without a large mass limit approximation is shown to be in fair agreement above 300 MeV/u, however important differences occur at lower energies.

轻离子分裂截面对于研究星际介质中的宇宙射线相互作用或屏蔽和组织中能量沉积的辐射防护考虑非常重要。重离子反应的磨损截面已使用大质量极限或光学势模型的 Eikonal 形式的 Glauber 模型进行了建模。^{在这里，我们使用 Glauber 模型制定了质子上4} He 碎片的磨损模型，避免了大质量限制，并包括最终状态相互作用的模型。^{使用质子靶将4} He 转化为³ He 或³ H的能量相关总截面、吸收截面、弹性截面和破裂截面的计算结果与 100 至 100,000 MeV/u 能量的实验非常一致。具有和不具有大质量极限近似的轻核的 Glauber 模型在 300 MeV/u 以上表现出相当一致，但在较低能量下会出现重要差异。
