Abstract
Single electron capture processes in Ne2+/Ar, Kr collisions were studied by aid of the high-resolution translational spectroscopy. At low collision energies (<1 keV) the dominant contribution to the Ne+-spectrum arises from Ne2+ ions in the metastable1 S 0-state, although it is the weakest component of the primary Ne2+ beam. Ne2+(3 P) and Ne2+*(1 D) projectiles play no important role due to unfavourable energy defects. Target excitation processes as well as transfer ionisation are considered as a possible explanation for different structures in the measured Ne+ spectra.
