Abstract

The determination of accurate appearance energy was analyzed for the interaction of electrons and protons with the RNA-base Uracil using rare gases. The electron energy range employed for the electron attachement studies was from about zero up to 15 eV. The slow electrons were colliding cellular RNA compound uracil. It was generally considered that the types of primary damage in DNA by ionizing radiation led to the most significant biological effect. The onset of the first resonance for the anions appeared at the relatively high electron of about 5eV for CN - and at 9eV for the O, which was followed by two resonances with the maximum at approximately 7eV and 10eV for CN -.
