Electron impact total cross sections for components of DNA and RNA molecules

Biomolecules, in particular DNA/RNA components are prone to high energy radiation damage which can occur due to primary, secondary or reactive processes [1]. We report electron impact total cross sections (Q$_{T})$, total elastic cross sections (Q$_{el})$ and total inelastic cross sections (Q$_{inel})$ for components of DNA and RNA molecules from threshold to 2000 eV. These components include Uracil (C$_{4}$H$_{4}$N$_{2}$O$_{2})$, Thymine (C$_{5}$H$_{6}$N$_{2}$O$_{2})$, Cytosine (C$_{4}$H$_{5}$N$_{3}$O), Adenine (C$_{5}$H$_{5}$N$_{5})$, Guanine (C$_{5}$H$_{5}$N$_{5}$O) and Phosphoric acid (H$_{3}$PO$_{4})$. We have employed Spherical Complex Optical Potential (SCOP) formalism [2] to calculate the total elastic cross sections, total inelastic cross sections and total cross sections.\\[4pt] [1] L.
