Abstract

In this thesis, the electronic structure and electrodynamical processes of atomic mercury and potassium are studied experimentally and theoretically. Experimental measurements were carried out by means of both conventional photoelectron spectroscopy and multielectron coincidence technique utilizing magnetic bottle time-of-flight electron spectrometer together with pulsed synchrotron radiation. The thesis focuses on the theoretical modelling and interpretation of the experimentally observed transitions and binding energies. The calculations were carried out with relativistic multiconfiguration Dirac-Fock (MCDF) and non-relativistic Hartree-Fock (MCHF) methods. Theoretical results were used to interpret the experimental data in order to study the electron binding energy level structure and electron transition dynamics of these atoms.
