Table 1
Main reactions creating He+ ions from charge exchange with solar wind alpha particles at an energy of 0.83 keV/amu.
| Reaction | Cross section (× 10-20 m2) | Reference |
|
|
||
| (4) He2+ + H | 8.53 ± 20% | Barnett et al. (1990) a |
| (5) He2+ + O | 4.00 ± 20% | Chanteur et al. (2009) b |
| (6) He2+ + CO | 3.58 ± 11% | Kusakabe et al. (2006) |
| (7) He2+ + CO2 | 4.91 ± 11% | Kusakabe et al. (2006) |
| (8) He2+ + H2O | 8.40 ± 10% | Greenwood et al. (2004) |
Notes.
Following Shematovich et al. (2013), same cross section as for He2++O2 → He++O
from Rudd et al. (1985a) above 5 keV/amu for lack of measurements. Recommendation of Chanteur et al. (2009) below 5 keV/amu.
