New FALP-MS measurements of , and dissociative recombination

Abstract
A series of measurements of the rate coefficient for the dissociative recombination (DR) of has been recorded. A value of was found for ions that are vibrationally cold. This is somewhat smaller than that measured previously by this group. The difference is ascribed to aerodynamic effects which affected our earlier measurement that have been eliminated in the present work. Results for and DR are also reported.
