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.
