摘要：

Cross section ratios sigma(2+)/sigma(+) for double and sigma(3+)/sigma(+) for triple relative to single ionization of argon, krypton and xenon atoms by positron impact were measured from threshold up to 1000 eV. All sigma(2+)/sigma(+) ratios exhibit double peak structures of which the high-energy structure is attributed to inner-shell processes, in agreement with theoretical estimates.
