The research described in this product was performed in part in the Environmental Molecular Sciences Laboratory, a national scientific user facility sponsored by the Department of Energy's Office of Biological and Environmental Research and located at Pacific Northwest National Laboratory. We perform molecular dynamics simulations of the chemical sputtering of
deuterated amorphous carbon surfaces irradiated by low energy deuterium atoms and
molecules ( = 30 eV/D). Particular attention was paid to the proper preparation of the
surfaces, as well as to the internal (rovibrational) state of impinging molecules. Sputtered
hydrocarbons are analyzed with respect to their mass, kinetic energy and angular
distribution. The sputtering yields are in good agreement with recent experimental results.
