| Abstract: | Experimental results on the sputtering of sulfur by MeV He ions are presented. It is shown that, for most of an Io surface, supposedly covered by sulfur, sputtering dominates sublimation in removing material. Sputtering cannot, however, be the sole supply of neutral sulfur for the Io torus. |
