Ionic recombination of Kr+ and Kr+2 with F− in dense buffer rare gases

Abstract
Rates, α, for the recombination of Kr+ and Kr+2 with F in various buffer rare gases (He, Ne, Ar, Kr, Xe) at 300 K are calculated for a wide range of gas pressures. For pressures 1–5 atm, the population of KrF* via recombination is greatest for Ne and Ar as third bodies, yielding α∼3×10−6 cm3 sec−1, while for pressures ≳10 atm, He is to be preferred as a buffer gas.
