Ever since the first description of the synthesis of molecules by impinging protons on ices, the possibility of formation of various molecules on cold surfaces by particle radiation has been widely discussed. The authors have recently studied sputtering of species by bombarding simple frozen gases such as water, carbon monoxide and ammonia with light ions. With these substances, only rather simple molecules were found. However, when bombarding methane, much larger molecules were detected in the sputtered beam-hydrocarbons containing up to at least 13 atoms. This suggests that bombardment of frozen methane by keV protons may produce large molecules in the Solar System.
