SPARC Topical Workshop 2016

It will be presented the COST action "Fundamental Parameters for Interactions of X-rays with Matter" submitted on April 2016. This action was supported by colleagues of nine european countries, including several members of the SPARC collaboration, and aims to establish an European network of the atomic physicists.

While quantum electrodynamics (QED) is usually referred to as the most accurately tested theory, its validity for electrons in very strong fields is still not tested with high accuracy. The strongest magnetic fields available in the laboratory are experienced by electrons in the groundstate of highly charged heavy ions which can be probed by hyperfine spectroscopy. Even though the ground state...
