Electron capture cross sections for multiply charged argon ions passing through nitrogen and krypton targets at energies from 10 to 110 keV

Abstract

Cross sections σif for electron capture processes of up to four electrons in single ion–atom encounters of multiply charged argon ions (up to Ar7+) in nitrogen and krypton targets are measured. The cross sections show no significant energy dependence in the investigated energy range from 10 to 110 keV. A plot of the cross sections for nitrogen and krypton target gases vs the projectiles initial charge state number i reveals a structure which is very similar to the structure previously reported for argon.
