Webb3 mars 2000 · Second, DNA damage by 3- to 20-eV electrons is highly dependent on the initial kinetic energy of the incident electron, particularly below 14 to 15 eV, where we observed thresholds near 3 to 5 eV and intense peaks near 10 eV. This is in sharp contrast to DNA strand breaks induced by similarly energetic photons, where both SSBs and …
