Abstract
Single and double ionization of helium in relatively small-impact-parameter collisions with 0.5--2.5-MeV/u O{sup 6,7+} ions is studied by associating target ionization with single-electron loss from the projectile. Double ionization is considerably enhanced (4--6 times) and found to deviate substantially from the energy and charge-state behavior observed for double ionization without accompanying electron loss from the projectile. The results are considered in terms of one- and two-step processes of double ionization.
