Intermediate-velocity atomic collisions: Electron capture and loss in 1042-MeV C ions

Abstract
The capture and loss of electrons for incident bare, one-, two-, and three-electron 1042-MeV carbon ions are studied. The one-electron-loss cross sections are compared with Glauber-approximation 1s ionization calculations, and a way of incorporating target-atom screening into the Glauber theory is proposed. The electron-capture cross sections agree reasonably well with eikonal-approximation results. The equilibrium charge states of the highest-energy C ions emerging from solid targets can be calculated accurately from gas-target equilibrium charge states using a theory incorporating excited-state effects.
