Calculated cross sections for electron elastic and inelastic scattering from DNA and RNA bases

Electron scattering cross sections from DNA/RNA bases are calculated in the 10 eV–10 keV energy range by combining screening-corrected aditivity-rule (SCAR) with ab-initio quasifree inelastic atomic potential. Similar calculations compare very favourably with available experimental data for benzene, C6F6 and tetrahydrofuran molecules. For DNA/RNA bases, where no experimental data is available, present results are compared with other theoretical values.
