Electrons Electron Ion Collisions Collisions between free electrons and ions belong to the most fundamental process in atomic physics. Within the AOF department, primarily electron-ion collisions with stable [...] stable heavy highly charged ions and with artificially synthesized radioisotopes are pursued. In a storage ring, the circulating ions repeatedly interact with the target electrons thus allowing investigations [...] and dedicated control of the isotope and charge state of the ion. At present, at ESR and at CRYRING@ESR three different classes of electron-ion collision experiments are carried out: Photon or electron

Depending on the requirements of the experiment standard targets on standard [...] or the like. 1.Procurement of the materials: We purchase the enriched isotopes for targets or as ion source material as well as special materials like for example Beryllium or very pure metal foils for

This allows a huge amount of combinations. The various products of the interaction between the heavy-ion beam and the target matter as for example fission products, recoil particles, or compound nuclei are
