Research Abstract

Surface atomic reactions on interstellar grains at low temperatures are investigated experimentally using newly developed experimental setup. Formation mechanisms of H_2, H_2O, CO_2, H_2CO, and CH_3OH are clarified. Measurement of sticking coefficient of H-atoms onto amorphous water ice enables us to deduce reaction rate constants. We also showed that amorphous water ice enhances reactivity at higher temperatures compared with pure solid reactants.
