Mean charge of ions (5Z125) emerging from aluminum foils

Abstract
We have determined the mean charge q¯ for projectiles 5Z125 exiting thin Al foils at a velocity v=v0. The results are compared with previous data for the same projectiles exiting thin C foils. In the region Zi15, the differences q¯(C)q¯(Al) are observed to be as large as solid-gas differences.
