Abstract

Absolute cross-sections for single-electron capture collisions of singly and doubly charged tungsten ions with inert gas (He, Ne, Ar, and Kr) and hydro-carbon gas (H2, CH4, C2H6, and C3H8) targets were derived experimentally. The measured cross-sections show strong power-law dependence on the first ionization potential of the target, whose slopes are independently identical to inert and hydro-carbon gas targets.
