Abstract
Recent results for the K- and L-shell ionization of silver and gold, r espectively, and the multiple ionization of argon, krypton, and xenon atoms by positron and electron impact will be discussed. The measured cross section ratios for triple relative to single ionization by posit ron impact decrease more rapidly towards threshold compared to electro n impact. This behavior is similar compared to results obtained for th e inner shell ionization of silver and gold, and attributed to the acc eleration or deceleration which incident electrons or positrons, respe ctively, undergo in the target nuclear field.
