Physics of Collisions and Photon Processes in Atomic, (Bio)

Molecular and Nano-sized Systems

1. Electron, ion and photon interactions with atoms and (bio) molecules (constituents or analogs of DNA molecules) relevant to radiation damage;

2. Interactions with surfaces (nano-capillaries, nano-dots) and atomic interferometry;

3. Photo-processes4. Information and expert systems in spectroscopy

and atomic collision physics and quantum informatics.

In 2003 The first COST experience

Radiation Damage in Biomolecular SystemsCOST Action P9 (2003-2007)

•Radiation damage induced by: indirect (diss, radicals, 2/3) and direct (deposition of energy in DNA and nearby 1/3) – Science (2000).•Presence of secondary electrons of subionizing energies (104 per ionizing particle).
