Scientific paper

In the light of the experimental results presented in a correlated paper on the production of organic residues by bombarding hydrocarbon frosts with fast ions, it is shown that a substantial amount of these materials can be synthesized on insterstellar grains and objects in the solar system by cosmic-ray fluence. The IR spectra of laboratory residues are shown. The main features are found at 2.9, 3.4, 6.2 and 6. 8 microns and resemble those observed on interstellar sources and on some meteoritic extracts. Some implications these results have on grain models and evolution and on the possible similarity between interstellar grains and objects in the solar system are also discussed.
