Phys. Rev. A 67, 022715 (2003) [5 pages]Charge transfer in keV O+(4S,2D,2P)-He collisionsReceived 15 November 2002; published 28 February 2003 Absolute differential cross sections (DCSs) are reported for charge-transfer scattering of (1–5)-keV O+(4S) ground-state and O+(2D,2P) metastable-state ions by helium atoms at angles between 0.2° and 6.3° in the laboratory frame. Estimated ground-state and metastable-state total cross sections are derived from these measurements. The present ground-state cross sections agree satisfactorily with previous measurements for energies above 2 keV and the metastable-state cross sections are consistent with the mixed-state data of Kusakabe et al. [J. Phys. Soc. Japan 59, 1987 (1990)]. The large differences between the ground- and metastable-state cross sections predicted by theory are not observed. © 2003 The American Physical Society URL:
