摘要：

The continuum-distorted-wave-eikonal-initial-state model is applied to the calculation of charged charge-state electronic stopping powers. The contributions from electron capture, excitation, and ionization are evaluated for pBAR, H+, He-2+, and Li-3+ projectiles impinging on H targets at energies of 10-1000 keV/amu. With the neutral H charge-state electronic stopping power obtained from the first Born approximation, charge-state fractions and total mean electronic stopping powers for H+ beams traversing H are calculated. Present results are compared with calculations using the first Born approximation, a one-center atomic-orbital coupled-channel code, and experimental data for H-2 targets.
