Jb. Greenwood et al., THE FIRST USE OF STATE-PREPARED BEAMS OF C2-SELECTIVE ELECTRON-CAPTURE COLLISIONS( IN STUDIES OF STATE), Journal of physics. B, Atomic molecular and optical physics, 29(16), 1996, pp. 599-603
The use of double translational energy spectroscopy has been successfu
lly demonstrated to allow studies of state-selective electron capture
with state-prepared primary ions. Excited product channels arising fro
m one-electron capture by 4 keV C2+ (S-1) ground-state and C2+ (P-3) m
etastable ions in collisions with argon have been separately identifie
