Chemical desorption of methanol induced by hydrogen abstraction–addition cycles on cold grain surfaces

Abstract We report ultra-high vacuum experiments on the non-thermal desorption of methanol (CH3OH) from cold dust-grain analogues under hydrogen-atom bombardment. Monolayer methanol films on polycrystalline gold, compact amorphous solid water (ASW, 10 ML) and 13CO ice (2 ML) are...
