A highly-charged ion impinging upon a neutral target atom will capture electrons into excited states of the projectile. If the velocity is much less than that of the target electrons, little direct ionization is expected, although appreciable target ionization has been reported for very highly charged ions. Recent studies on both transfer and ionization for Ar{sup q+} (6{<=}q{<=}17) and O{sup +8,7} on Ar and He target shave been performed for projectile velocities between 0.2 and 1.7 a.u. The measured quantities include charge-state-correlated differential cross sections, K-x-ray emission, and longitudinal recoil- ion momentum transfer, from which Q values can be deduced. Non-negligible direct ionization is observed. Information is extracted on both the primary transfer process and the decay of the multiply excited projectile states formed. Comparisons with model predictions will be made.
