Abstract (from CDS):

The formation of water molecules from the reaction between ozone (O₃) and D-atoms is studied experimentally for the first time. Ozone is deposited on non-porous amorphous solid water ice (H₂O), and D-atoms are then sent onto the sample held at 10 K. HDO molecules are detected during the desorption of the whole substrate where isotope mixing takes place, indicating that water synthesis has occurred. The efficiency of water formation via hydrogenation of ozone is of the same order of magnitude as that found for reactions involving O-atoms or O₂ molecules and exhibits no apparent activation barrier. These experiments validate the assumption made by models using ozone as one of the precursors of water formation via solid-state chemistry on interstellar dust grains.
