dc.description.abstractThe subject of this Doctoral Dissertation is the study of atomic systems in external static electric field, which can be described using models with one or two active electrons. The main aim of the dissertation is determination of the Stark shift of the lowest state and the ionization rate (or the electron detachment rate in the case of ions) depending on the field strength. The calculations are performed using the complex rotation (scaling) method with the expansion of trial wave functions in the basis of Coulomb Sturmians. The sistems analyzed here are the hydrogen atom, alkali-metal atoms (lithium, sodium, potassium, rubidium, cesium, francium), helium atom, and the hydrogen negative ion. For alkali-metal atoms several types of pseudopotential are used, while the two-electron systems are studied by applying the exact two-electron description as well as single-electron approximations. A good agreement with the results of other authors, who used similar (numerical) methods, and with the formulas of standard theoretical description in the case of weak field, is obtained. An important result is also an analysis of applicability of the methods and models used for the considered system.en
