Abstract
The mean charge, q¯, has been measured for projectiles 5<~Z1<~26 exiting thin carbon foils at velocities 0.8<~vv0<~1.0. It is observed that q¯(Z1) increases strongly with Z1 with a broad peak occurring at Z115. It is shown that much of the enhancement can be accounted for by post-foil Auger decay of projectile inner-shell vacancies.
