Single- and double-electron loss of [Formula Presented] in collisions with [Formula Presented], [Formula Presented], and CO

Measurement of absolute, total cross sections for single- and double-electron detachment of [Formula Presented] projectiles in sulfur hexafluoride, methane, and carbon oxide has been made. The relative energy range under investigation was from 1 to 5 keV. The resulting cross sections for the single-electron loss of [Formula Presented] in [Formula Presented] exhibit a flat behavior, whereas for methane and carbon monoxide the single detachment cross section increases with the energy. A free-collision model for electron loss was applied, and very good agreement was found for [Formula Presented], while for the other targets there is a departure of the trend of the experimental data. A comparison with the results from other research laboratories is given. The measured double-electron detachment cross sections are roughly one order of magnitude smaller than the single detachment cross sections.
