A presentation of three ab initio atomic structure calculation projects

På svenska

Author

Summary, in English

Three theoretical atomic structure projects of interest for the astrophysical community and the lightning industry which are partially finished will be presented. Extensive ab initio calculations of properties of astrophysical interest has been done or are under its way for Ga I, Ga II, Ga III, In II and In III. The aim of the project is to also make calculations for In I, Tl I, Tl II and Tl III. Results will be presented for gf-values, hyperfine structure, hyperfine quenching, isotope shift and gf-factors for parts of the Ga I and Ga II systems to give a flavor of what we are doing. Large spectroscopic calculations of transition probabilities for some of the neutral noble gases has been done or are under its way. This project is done as a part of a fluorescent light project in which the goal is to simulate the plasma in a fluorescent tube. A large number of transition probabilities will be presented for Kr I. Developing of programs as a part of the MCHF and GRASP packages has been done for implementing the effects on ions in an external magnetic field. An example of our treatment will be given
