Recent experimental data for equilibrium charge-state fractions of 6.0 MeV/u ions with the atomic numbers Z equals 6-26 passing through carbon foil are described in terms of the charge-exchange cross sections, based on the four-charge state approach. It was found that the reasonable agreement could be obtained only if the target-density effects are adequately accounted for. In addition, the present treatment allows one to estimate the distributions of excited states of the exit ions on the basis of equilibrium charge-state fractions and ionization and electron-capture cross sections calculated with the density effects included. The present analyses show the importance of the target-density effects in collisions of fast ions with solid targets.
