An international collaboration led by a research group from GSI/FAIR in Darmstadt, Germany, has achieved the first measurement of the chemical stability of a superheavy element compound. The focus was on the hexacarbonyl complex Sg(CO)₆ of seaborgium (Sg, element 106). The result: The bond between the seaborgium atom and a carbonyl ligand is weaker than expected based on its position in the periodic table. Relativistic effects are the cause. The results are published in the journal Nature.

Staff members from the Heidelberg Ion Beam Therapy Center (HIT) recently visited GSI and FAIR. The focus was on the close connection between heavy-ion therapy developed at GSI —a groundbreaking innovation in modern cancer treatment that is continuously being advanced at GSI/FAIR—and its successful implementation in clinical practice at HIT. The visit offered the guests ...

This year's SPARC collaboration PhD Prize was awarded to Dr. Jan Richter from Physikalisch-Technische Bundesanstalt (PTB) and the Leibniz University Hannover, Germany, for his thesis entitled “Highly charged ions as a tool for fundamental physics and tests of the Standard Model”. The ceremony took place during the 23rd SPARC Topical Workshop at the Institute of Modern Physics, Chinese Academy of Sciences, in Huizhou, China, where the award was handed over by Professor Reinhold Schuch from…

A research team from GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has studied four superheavy nuclei with a newly developed experimental technique. ANSWERS measures thus far inaccessible properties, which are important for understanding element synthesis in the Universe. The results are published in Physics Letters B.

In March 2026, scientists succeeded in transporting antiprotons by road for the first time in a purpose-built trap loaded on a truck. The BASE collaboration, which realised this experiment at the European Organisation for Nuclear Research (CERN) in Geneva and of which GSI/FAIR is a member, now presents its findings and experiences from this pioneering experiment in the scientific journal Nature. Antiprotons could be stored for the first time ever for more than a month in a mobile transport…

34 students came from 16 countries this summer to participate in the GSI/FAIR Summer Student Program. For eight weeks, they were able to immerse themselves in the daily life at an international particle accelerator center. Our yearly photo contest offers exclusive insights into the program.

This Saturday, around 20 stations welcomed visitors to Frankfurt’s second Science Festival, bringing science to life for people of all ages. On stage and at interactive stations on the central Roßmarkt square, guests had the chance to explore the research of the Frankfurt Alliance, a network of 16 research institutions from the Frankfurt/Rhine-Main region. GSI/FAIR offered insights into the function of particle accelerators and their scientific work with two hands-on experiments.

A consortium comprising persons from CERN, the Cockcroft Institute, GSI/FAIR, and the University of Liverpool has been awarded the prestigious “Faraday Cup Award” for the development of a beam-induced fluorescence monitor, referred to as the “Beam Gas Curtain Monitor.” The award for innovations in accelerator beam instrumentation was presented at the “International Beam Instrumentation Conference 2026 (IBIC).”

An international research team led by the University of Edinburgh, in collaboration with researchers from GSI/FAIR, Justus Liebig University Gießen (JLU), and other partner institutions, has developed a new experimental approach to studying short-lived radioactive molecules. This work lays the cornerstone for a new generation of precision experiments capable of investigating fundamental questions in physics — ranging from the search for physics beyond ...
