The charge-state distributions and production cross sections of Ne recoil ions produced through pure ionization, electron capture, and electron loss processes of projectile Ar ions have been determined for 1.05-MeV/amu Ar[sup [ital q]+]+Ne ([ital q]=4, 6, 8, 10, 12, 14, and 16) collisions using a projectile-ion-recoil-ion coincidence technique. Recoil ions in low charge states, in particular, singly charged ions, are produced predominantly through pure ionization without any change of projectile charge. Electron loss or capture processes of projectiles, though weak relative to the pure ionization, are found to result in an enhancement of the multiply charged recoil ions. The average charge [l angle][ital i][r angle][sub [ital q],][ital q][sub [prime]] of recoil ions in a specific process, Ar[sup [ital q]+]+Ne[r arrow]Ar[sup [ital q][prime]+]+Ne[sup [ital i]+], is found to increase with increasing projectile charge [ital q] and with the number of the lost or captured electrons from or into projectiles.
