A photoionization study of the charge transfer reactions - Xe/+/ + O2 yields O2/+/ + Xe and O2/+/ + Xe yields Xe/+/ + O2

The charge transfer reactions: Xe(+) + O2 yields O2(+) + Xe and O2(+) + Xe yields Xe(+) + O2 were studied using photoionization mass spectroscopy. It is shown that the reaction of Xe(+)(2P-3/2) ions with O2 molecules is much more efficient than the reaction of Xe(+)(2P-1/2) ions with O2 molecules. The charge transfer reaction of O2(+) ions with Xe atoms was detected for O2(+) ions in the a 4Pi-u state.
