Anisotropy and charge effect in collisions of ions with biomolecules.
Charge transfer dynamics induced by collision of carbon ions with biological targets has been investigated theoretically by means of ab-initio quantum chemistry molecular methods. The series of pyrimidine nucleobases, thymine, uracil and 5-halouracil with similar skeleton and different substituents have been considered. The charge effect between C(6+) and C(4+) carbon ions is analyzed as well as the anisotropy of the electron exchange process.
