Stopping Power of Fast Channeled Protons in the Impact Parameter Treatment of Atomic Collisions

  • K. Dettmann


The energy loss of protons, passing through crystals in a random direction with an energy E ≥ 1 MeV, is due to electronic excitation and can be explained quantitatively by the Bethe-Bloch formula [1] for the average energy loss per unit path length or the electronic stopping power Sr = - dE/dx. In a channeling situation, however, small impact parameters are avoided and the Bethe-Bloch theory no longer applies.
