We present results of hydrogen recombination reactions on dust grain analogues: measurements of the formation efficiency, kinetics and energetics of diffusion and reaction, and translational energy of ejected molecules. An analysis of the mechanisms of formation and of the effects of the morphology of surfaces of the dust analogues on this reaction is also given. We illustrate the use of laboratory data in modeling ISM chemistry.
We are grateful to NASA (through grant NAG5-11438) and the Italian Ministry for University and Scientific Research (through grant 21043088 CNR) for financial support.
