State-selective and total one-electron capture in Nesup(q+)-Li collisions (q = 1, 2, E <= 30q keV)

Cross sections for total one-electron capture and emission of important VUV lines produced by one-electron capture in collisions of Ne+ and Ne2+ ions with Li atoms have been measured at ion impact energies between 5 and 30 keV, for q=1, and 20 and 60 keV, for q=2. Excitation cross sections were derived and compared with empirically calculated data assuming one-electron transitions in the quasimolecular two-state approximation. In deriving the cross sections both metastable primary ion beam fractions and long-lived secondary ion states were quantitatively dealt with. (author)
