Physics of collisions and photo processes in atomic, (bio)molecular and nanosized systems

Contemporary progress in science, medicine and technical development is closely related to the understanding of fundamental processes at atomic and molecular level. Study of atomic particles and photon interactions with atomic particles in gases, liquids and at surfaces is the subject of this project. Lasers, synchrotron and broadband UV radiation will be used as the sources of photons. Interactions with biomolecules will be studied and excitation-emission spectra and fluorescent life times will be investigated. Photo processes in strong and attosecond laser fields will be studied theoretically. Intensity and influence of solar UV radiation will be measured. The experiments of binary collisions of monoenergetic electrons with metal vapour atoms, di- and triatomic molecules, biomolecules, ions and metastables will be conducted. Processes of elastic scattering, excitation, ionization and dissociative electron attachment will be investigated and cross sections will be determined. The idea of the project is to extend the present experiments to collisions with nanoparticles, so the design of new nanoparticle source is proposed. We will also study electron transmission through nanocapillaries, transport properties of thin films and quantum dots, the heavy particle collisions, atomic processes in atmosphere, atomic intereferometry and quantum informatics. The special interest of the project is in better understanding of radiation damage processes and electron controlled reactions.
