Temporary electron localization and scattering in disordered single strands of DNA
- Groupe de Recherches en Sciences des Radiations, Faculte de medecine, Universite de Sherbrooke, Sherbrooke, Quebec, J1H 5N4 (Canada)
We present a theoretical study of the effect of structural and base sequence disorders on the transport properties of nonthermal electron scattering within and from single strands of DNA. The calculations are based on our recently developed formalism to treat multiple elastic scattering from simplified pseudomolecular DNA subunits. Structural disorder is shown to increase both the elastic scattering cross section and the attachment probability on the bases at low energy. Sequence disorder, however, has no significant effect.
