Abstract

Current models describing the ionic charge states in solids have been reconsidered by noticing the shell effect of ionic charge distributions observed behind a solid target. For this purpose, the source of the shell effect has been investigated by performing Monte Carlo calculations. As a result, the shell effect, which originated inside the foil, has been found to be preserved outside the foil, which leads to the argument that the post-foil Auger electron emission plays only a minor role in the explanation of the difference of heavy ion mean charges between solid and gaseous media. It is concluded that the Betz-Grodzins (BG) model representing the density effect of ionic charge states is not adequate for most of the collisions.
