英文摘要	we investigated the irradiation of low temperature (h2o)-o-18/n-2 ice mixtures with energetic electrons in an ultrahigh vacuum chamber. the newly formed species, such as nitric oxide ((no)-o-18), nitrous oxide ((nno)-o-18), hydrogen peroxide ((h2o2)-o-18) and hydrazine (n2h4), were identified in the experiments with infrared absorption spectroscopy and mass spectrometry. the results suggest that the unimolecular decomposition of water molecules within water ices at 10 k can lead to the formation of transient, suprathermal oxygen atoms. these oxygen atoms may play an important role in the formation of oxygen-containing biomolecules such as amino acids and sugar, as well as the decomposition of the biomolecules in the ices.
