Interaction of Nucleic Acid Bases Molecules With Low-Energy Electrons

Summary

    Electron impact excitation, ionization and dissociation of gas-phase cytosine molecules were studied by optical and mass-spectrometric methods in the energy range of 0 to 300 eV. The luminescence spectra of cytosine and its dissociative excitation products we¬re obtained within the region of 200 to 600 nm. Excitation functions for molecules in question were measured. Possible biophysical and radiobiological applications of the ob¬tained results are discussed.
