Abstract
Recent experimental results for the multiple ionization of argon by po sitron impact have been reanalysed. Absolute cross sections for the do uble and triple ionization of argon were obtained from measured ratios of double-to-single and triple-to-single ionization, using known cros s sections for single ionization and for positronium formation. Distin ct differences compared to similar results for electron impact are not ed.
