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 4 He fragmentation on protons using the Glauber model
avoiding the large mass limit and include a model for final state interactions. Calculations of …
