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.
