Objectives:
Understanding of structure of isolated atoms and simple molecular systems in the field (free) environment and knowledge of their response upon excitation with photon, electron and other atoms (ions).

Competences:

Knowledge of modern experimental techniques and basic theoretical approaches in atomic and molecular physics. Ability to implement numerical algorithms for calculation of the atomic wave functions and of the other system properties.

Knowledge and understanding:
Understanding of the basic atomic molecular structure and of their excitation and relaxation pathways in the field (free) environment. Knowledge about research and analitycal atomic spectroscopies.

Application:
The acquired knowledge allows for a solid understanding of the atomic and molecular structure and dynamics when these systems are interactiong with photons, atoms and charged particles (electrons and ions). This is the basis for more detailed studies of atomic relaxation, of manipulation techniques on a scal of a single atom and for spectroscopic techniques that are nowadays extremely important in the material analysis.

Reflection:
Use of the quantum mechanics to describe excitation and relaxation of correlated manybody systems.

Transferable skills:
The acquired knowledge about structure and dynamics of atoms and simple molecular systems in field (free) environment forms a basis for understanding of the more complex szstems such as macromolecules and the condensed matter.

Lectures, exercises, research workshop – work in the field.
