O+ + Si0 O0 + Si+(3s 3p2 4P)	5.47	0.15		[Si II] 2329-2351 Å
O+ + S0 O0 + S+(2P)	3.26	0.22		[S II] 4069, 4076, 6716, 6731, 10 287-10 370 Å
O+ + Fe0 O0 + Fe+ (excited)	5.72	many transitions		multiple lines; rate from Rutherford & Vroom (1972)

Notes: it is assumed that the atoms and ions are in their ground states (or excited fine-structure states) before the charge-exchange reaction. denotes the difference in the ionization potentials of atom and ion in their ground states, denotes the same difference for outgoing atom and ion in specified states, and is the charge exchange rate estimate. Only excited state classification is shown.
