The course prepares the student for further studies in applied atomic and molecular physics, basic material physics and research in atomic and molecular physics.
After completing the course the student should be able to
master both experimental and theoretical working methods in atomic and molecular physics for making correct evaluations and judgments
carry out experimental and theoretical studies on atoms and molecules, with focus on the structure and dynamics of atoms and molecules
account for models, terminology and working methods used in experimental and theoretical atomic and molecular physics
handle relevant experimental equipment and evaluate the results obtained
Repetition of quantum mechanical foundations: stationary states; expectation values; electronic states and wave functions
One-electron atoms: energy levels and wave functions; spin-orbit interaction; relativistic and QED-related effects; electronic transitions; electric dipole approximation; quantum numbers and selection rules; angular momenta and coupling schemes; radiation of higher order; radiation-less transitions.
Helium: approximations for the Schrödinger equation; Coulomb- and exchange integrals; ground state and excited states; wave functions and their symmetry; spectra.
Molecular symmetry and motion: Symmetry and symmetry operations; point groups; group theory; representations; analysis of molecular motions.
Molecular quantum mechanics and beyond: H2+-molecule, H2-molecule, bonding, LCAO-MO-approximation; symmetry adapted molecular orbitals; electronic states and electron correlations; rotations and vibrations including symmetry analysis; potential curves; transitions between different states.
Molecular spectra: Rotational- and vibrational resolved spectroscopy; electron spectra ; Franck- Condon principle; interaction with electromagnetic radiation; semi-empirical calculation methods.
Computer-assisted calculations and simulations, such as extended Hückel and ab initio.
Laboratory work: optical spectroscopy, atomic and molecular calculations, research laboratory visit (x-ray generation and photoelectron spectroscopy).
Lectures and tutorial classes, student presentations on selected topics and guest lectures on up-to-date research, compulsory practical laboratory exercises and problems ; teaching will also be given in forms of demonstrations and supervision in particular in the context of the practical laboratory exercises and tutorial classes.
Active participation in class, oral presentation, hand-in exercises. Laboratory experiments.
