Cím:	Theoretical treatment of direct and indirect processes in ion-biomolecule collisions / E. Bene, E. Rozsályi, Á. Vibók, G. J. Halász and M.C. Bacchus-Montabonel
Dátum:	2008
Megjegyzések:	Atomi Ütközések Osztálya, MTA-Atommagkutató Intézet Test case collision systems for direct and indirect processes in the action of radiation on the biological medium have been investigated theoretically by means of ab initio quantum chemistry molecular methods followed by a semiclassical dynamical treatment. As a direct process, we have studied the charge transfer of the RNA base uracil on Cq+ Ions (q=2,4). The process depends strongly on the orientation of the projectile towards the uracil target, in particular for the C4+ + uracil reaction, and shows a significant delocalization of the pi electrons of the uracil ring towards the carbon ion. The collision of C2+ ions on the OH radical has been also investigated as a model of the action of ions on OH radicals created in the medium, in order to have a look to some possible processes. The approach in the linear geometry with consideration of the relaxation of the OH tar-et has been considered.
