Theoretical modelling and experimental analysis of heavy atomic systems.

Over the past 15 years, part of our work has been focused on the study of the atomic structure and the determination of radiative parameters in neutral and lowly ionized heavy atoms (37 < Z < 86). These elements have attracted little interest in the past due to the complexity of their atomic structures, to the poor knowledge of their spectra and to the difficulty to perform experimental measurements. They present however a great interest in the development of other scientific areas such as astrophysics and plasma physics. In our talk, we will give an overview of the recent progress performed in the theoretical modelling and the experimental analysis of such heavy elements. We will also show some applications of the atomic data obtained in our work for the interpretation of the spectra observed from astrophysical and laboratory plasmas.
