Notes. For Ge, Se, and Br, the spin-orbit coupling rate coefficient found for Cl+, 10-12 cm3 s-1 (Pradhan & Dalgarno 1994), is adopted as an upper limit when the rate from radial coupling falls below that value. SO coupling is not relevant for CT reactions involving neutral Kr, Rb, and Xe, and hence we set the rate coefficient to the canonical radiative CT rate (10-14 cm3 s-1; Butler et al. 1977) when the radial coupling rate coefficient is smaller than that value. Note that radiative CT does not occur for the endoergic reaction Kr0 + H+ → Kr+ + H + δE.
