In close collaboration with scientists from all over the world, the groups in GSI's Atomic Physics Division (AP) exploit the possibilities of the GSI accelerator complex. This combination of a linear accelerator (UNILAC), heavy-ion synchrotron (SIS), fragment separator (FRS), and the experimental storage ring (ESR), makes it possible to accelerate, store, and cool relativistic ion beams of every element from hydrogen to uranium. Stable or radioactive isotopes are being investigated. The main interest is focused upon the very highly charged heavy ions. These unique research possibilities stimulate a broad range of interesting experiments in both atomic and nuclear physics, as the following publications show.
