Abstract

Binary, layered ices comprising of benzene (C₆H₆) on water (H₂O), on methanol
(CH₃OH) and on diethyl ether (CH₃CH₂OCH₂CH₃) have been irradiated with 250
eV electrons. Molecular hydrogen (H₂) production is observed by quadrupole mass spectrometry to be competitive with (in the case of H₂O), and dominate over (in the case of the organic substrates), C₆H₆ desorption. While very preliminary, these results suggest that desorption induced by interaction of organics-rich icy solids with ionising particle radiation may not be the principle route to gas phase complex organic molecules observed in cold dense environments.
