The investigations of the positive ionization processes of nucleic acid base guanine were made using crossed electronic and molecular beams. Mass-spectrums were measured and absolute and partial sections of guanine molecules ionization were determined. The energy dependence was determined for the cross-section of formation positive guanine ions at the electron energy interval from the formation threshold up to 200 eV. The total positive guanine ions production cross reaches the (3,2 ± 0,15)·10-15cm2 at the 95 eV electron energy.
