Ionic recombination of rare-gas atomic ions <i>X</i>+ with F− in a dense-gas <i>X</i>

Abstract

Rates for the recombination processes X++F−+X→XF*+X, (X≡He, Ne, Ar, Kr, Xe) at 300 K are calculated for pressures of the background gas X in the range ∼0.1–50 atm. Rates as high as (2–7) ×10−6 cm3 sec−1 are obtained for pressures 1–5 atm of Xe→He, and in general decrease with increasing ionic mass, except at low gas densities.
