Abstract (from CDS):

The rate coefficients for 13 806 partial inelastic processes in low-energy Fe+ + H and Fe2+ + H collisions are calculated by means of a quantum simplified model including 118 quintet molecular states of FeH+: 117 covalent and ground ionic states. The calculations are performed within the 5Σ^+, 5^Π and 5Δ molecular symmetries. The largest rate coefficient, with a value of 7.47 x 10–8 cm3 s–1 at T = 6000 K, corresponds to a neutralization process. In addition, 57 partial neutralization processes have rates exceeding a value of 10–8 cm3 s–1 and many processes have rates in the range 10–9-10–8 cm3 s–1. Among (de-)excitation processes, the largest rate coefficient has a value of 5.66 x 10–9 cm3 s–1. Nevertheless, there are many partial (de-)excitation processes with rate coefficients in the range 10–9-10–8 cm3 s–1. Collisional processes with large-valued rates are expected to be important in astrophysical applications.
