摘要：

Erosion and decomposition of solid hydrocarbons under bombardment with proton, helium and argon ions is studied as a function of ion energy in the keV÷MeV range. Methane (10K), benzene (77K) and polystyrene (300 K) show a strong molecular hydrogen emission with a complex behaviour as a function of ion fluence (1012÷1017ions/cm2). Dimer formation is observed in the irradiated volume and high yield is measured (200 dimers/ion) for all the samples. At high fluence a three-dimensional carbon-hydrogen network is formed whose thickness is proportional to the ion range. © 1990 Società Italiana di Fisica.
