Abstract
In the present study we investigate electron interactions with important cell molecules, nucleosides viz. Adenosine, Guanosine, Cytidine, Thymidine and Uridine from ionisation energy to 5000 eV. While nucleobases are studied extensively, these nucleosides have not been investigated enough. We focus to quantify various molecular processes induced by electrons through inelastic (Qinel), ionisation (Qion), electronic excitations (Qexc), elastic (Qel) and total (Qtotal) cross-sections. We used the complex optical potential approach to compute inelastic and elastic probabilities and employed complex scattering potential-ionisation contribution method to perform the calculations to bifurcate inelastic processes in to discrete and continuum contribution. This work is the first report of all these quantities, except Qion, to investigate the electron induced local chemistry of these important DNA/RNA compounds.
