electron stopping (any B, lower straight lines).

6. Summary

Up to now we limited our investigation to proton stopping by target electrons. In the verylow-velocity regime V ≤ Vthi, the target protons can also contribute significantly as evidenced

We developed and extensively used a kinetic approach based on a binary collision formulation and suitably regularized Coulomb interaction, to numerically document for any value of the
