Atomic mean excitation energies for stopping powers from local plasma oscillator strengths.
Mean excitation energies for stopping by isolated atoms are accurately predicted by the plasma absorption spectrum associated with the atomic orbitals when the plasma frequency shift due to individual electron motion proposed by Pines [Phys. Rev. 92, 626 (1953)] is incorporated.
