Chemical Rates on Small Grains and PAHs: C^+ Recombination and H_2 Formation

Mark G. Wolfire, A. G. G. M. Tielens, David Hollenbach +1

We use observations of the CI, CII, HI, and H_2 column densities along lines of sight in the Galactic plane to determine the formation rate of H_2 on grains and to determine chemic…
