11.7 Reaction 2.0b p + H2(v = 0) → H + 2 + · · · , ratio H + 2 /H2<br />
gain of H + 2 : production by CX (ion conversion, proton impact) on cold (0.1 eV) H2(0), vibr.<br />
ground state only. Only dependence on one temperature Tp.<br />
loss of H + 2 : coll. rad. model for H2, H + 2 , Sawada, Fujimoto, [7], electron impact dissociative<br />
recombination, excitation <strong>and</strong> ionization. Total loss: electron density independent.<br />
Note: the contribution 2.0a to this ratio from electron impact processes leading to H + 2 is electron<br />
density dependent, because the effective electron impact ionisation is density dependent. This<br />
contribution to the ratio is given in the next chapter under the “double-polynomial fits”.<br />

11.8 Reaction 2.0c p + H2(v) → H + 2 + · · · , ratio H + 2 /H2<br />
gain of H + 2 : coll. model for vibr. excitation, Greenl<strong>and</strong>, Reiter, [10]), <strong>and</strong> then: H + 2 production<br />
by CX (ion conversion, proton impact) on these H2(v). <strong>The</strong> density dependence on vibrational<br />
distribution P (v) of H2(v) vanishes for ne = np. Only dependence on one temperature for<br />
Te = Tp.<br />
loss of H + 2 : coll. rad. model for H2, H + 2 , Sawada, Fujimoto, [7], electron impact dissociative<br />
recombination, excitation <strong>and</strong> ionization. Total loss: electron density independent.<br />
Assumptions:<br />
EH2 = 0.1 eV, Ti = Te, vibrational distribution P (v) in electr. ground state of H2 with no<br />
coupling to B,C states, hence: also gain rate of H + 2 due to this process is independent of ne.<br />
B,C coupling to vibr. states is non-linear in density <strong>and</strong> would hence make this ratio density<br />
dependent.<br />
