Abstract
Visible light emission spectra during collisions between O5+ ions and He atoms in the range of 200–800 nm at different projectile energies (4.06–5.31 keV-u−1) have been measured. Emission spectra show that there are three channels of excitation in the O5+-He collision system: (i) single-electron capture into excited states; (ii) double-electron capture into excited states; (iii) direct excitation of target atoms. There are transitions between states with comparably high quantum numbersnl. The absolute emission cross-sections of every spectral line are calculated. The relations of these cross-sections with the energy of the projectiles are studied.
