Outline of Final Research Achievements |
Although it has been pointed out that secondary electrons with low energy, that are produced from high-energy radiation, can cause significant biological damage, its dynamical mechanisms have not yet been fully understood. We have performed systematic theoretical research on dynamics of radiation damage of biomolecules by low-energy electrons from a theoretical viewpoint. We have explored the binding mechanism of excess electrons in various biological systems including base pair using quantum chemical calculations. In addition, we carried out quantum dynamics simulations that can describe all atomic motions quantum mechanically. The results provide real-time understanding of radiation damage mechanisms by low-energy electrons.
