Reaction rate coefficients from UMIST RATE12 (1) used in the analytical formula from Aikawa et al. (2015).
| i | Reactions | α | β |
|---|---|---|---|
| 1 | H2 +  |
– | – |
| 2 |  |
2.08(−9) | 0.0 |
| 3 |  |
1.61(−9) | 0.0 |
| 4 | HCO + + e → H + CO | 2.40(−7) | −0.69 |
| 5 |  or H +H + H |
7.20(−8) | −0.5 |
Notes. Rate coefficients are given in the form of k = α ×
and
A(B) stands for A × 10B.
