Single electron loss of Kr+ ions in gaseous media

Abstract

Differential and total cross sections for single electron losswere measured for Kr+ ions on gaseous media in the energyrange of 1.0 to 5.0 keV. The single electron loss crosssections for all the targets studied are found to be in theorder of magnitude between 10-22 and 10-20 cm2,and show a rapid monotonically increasing behaviour as afunction of the incident energy; no remarkable differences inthe energy dependence of σ12 were found for any atomstudied. The single electron loss cross sections show a weakerZt dependence in the large Zt region than that given bythe Bohr formula. A striking feature of the results is theexperimental evidence of saturation in the single electron losscross section as the nuclear charge of the target increases.
