1. Electron Recombination with Small Molecular Ions
Sammanfattning : In this thesis I have theoretically studied electron recombination processes with small molecular ions. In these kind of processes resonant states are involved. To calculate the potential energy for these states as a function of internuclear distance, structure calculations and scattering calculations have to be performed. LÄS MER
2. Spectroscopic Studies of the Elements Ba, Fe, Ga, In and Ru
Sammanfattning : New measurements of the elements Ba, Fe, Ga, In and Ru are reported. The analysis of barium contains new wavelengths, improved energy level values and new values of the ionization limit in both Ba I and Ba II. Oscillator strengths and radiative lifetimes in Fe II, as a part of the FERRUM project, are reported. LÄS MER

4. Atomic and molecular density-of-states by direct Lanczos methods
Sammanfattning : .... LÄS MER
5. A class of infinite dimensional stochastic processes with unbounded diffusion and its associated Dirichlet forms
Sammanfattning : This thesis consists of two papers which focuses on a particular diffusion type Dirichlet form where Here is the basis in the Cameron-Martin space, H, consisting of the Schauder functions, and ν denotes the Wiener measure.In Paper I, we let vary over the space of wiener trajectories in a way that the diffusion operator A is almost everywhere an unbounded operator on the Cameron–Martin space.
