I am attempting to model energy deposition from ions in air. I am still working to make certain I have included all the necessary physics.
When a heavy ion (i.e. proton, deuteron, triton, alpha, N+, O+) is slowing down, some of its energy is dissipated into heating the air, rather than to ionization. This process is sometimes called “nuclear stopping” and is a greater percentage of the energy loss at E/m < 200 keV/amu.
Is there a choice one could make in the physics list to demonstrate energy loss through nuclear stopping rather than ionization?
I am currently using the QGSP_BERT_HP physics list. I understand to answer the above question I may have to write my own slimmed down physics list. Guidance on what to include in that list would be greatly appreciated.
thanks for any advice
