Single electron capture by state-selected multiply charged Arq+ ions (q = 3,4)

Abstract State-selective single electron capture by multiply charged Ar q + ions ( q = 3, 4) has been studied in rare gas targets with the aid of double translational spectroscopy. The energy gain spectra have been measured using different projectile beams, either extracted from an electron beam ion source or produced by electron capture reactions in an additional preparation cell. The influence of metastable projectile states as well as the reaction channel identification in complex systems are discussed.
