Absolute cross sections for single- and double-electron capture, and single-electron loss, have been determined for O{sup 7,8+} ions colliding with Ar and Ne in the energy range 8{endash}40 MeV. Double-electron-capture cross sections were found to be factors of 5{endash}10 smaller than the single-electron capture cross sections. The present results for electron capture from Ar are systematically larger by about 30{percent} than the corresponding cross sections determined previously by Macdonald and Martin [Phys. Rev. A {bold 4}, 1965 (1971)]. The present single-electron-capture cross sections agree well with the empirical scaling rule of Schlachter {ital et al.} [Phys. Rev. A {bold 27}, 3372 (1983)]. {copyright} {ital 1997} {ital The American Physical Society}
