The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high temperatures and densities in the merger scientists conjecture a phase-transition where neutrons dissolve into their constituents: quarks and gluons. In the current issue of Physical Review Letters, two international research groups report on their calculations of what the signature of such a phase…

An international group of researchers including participants from GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt and its two branches, the Helmholtz Institutes Mainz and Jena, have determined the first ionization potentials of the artificially created elements fermium, mendelevium, nobelium, and lawrencium. The data unambiguously show that the actinide series ends with lawrencium. The results have been published in the Journal of the American Chemical Society (JACS).

Die öffentliche Vortragsreihe „Wissenschaft für Alle“ von GSI und FAIR in Darmstadt startet am 23. Januar 2019 mit ihrem neuen Vortragsprogramm. Den Auftakt macht Ulf von Rauchhaupt von der Frankfurter Allgemeinen Sonntagszeitung mit seinem Vortrag "Die Ordnung der Stoffe – Geschichte und Geschichten rund um das Periodensystem der chemischen Elemente". Der Vortrag läutet ein besonderes Ganzjahresprogramm für die Vortragsreihe ein: Das Jahr 2019 ist ein Jahr der Jubiläen.

To create a European science cloud, allowing universal access to research data through a single online platform – that is the aim of the European Open Science Cloud (EOSC) initiative launched by the European Union member states. The EU project ESCAPE has now received a grant. ESCAPE (European Science Cluster of Astronomy & Particle physics ESFRI research infrastructures) aims to address the common Open Science challenges in astronomy and particle physics research domains. FAIR and GSI are…

Intense discussions and numerous new contacts — the FAIR construction project’s participation this year in the internationally renowned real estate trade fair Expo Real was once again very successful. The project’s dynamic progress attracted strong interest from professionals and trade fair visitors. Over a period of three days, an extensive presentation of the construction planning and the next steps toward the realization of the unique particle accelerator facility FAIR (Facility for…

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma. Then, in a phase…

Twenty years ago, researchers at GSI Helmholtzzentrum für Schwerionenforschung began to conduct clinical studies of an innovative cancer treatment that used accelerated carbon ions. In August and September 1998, the first patients were treated with a complete course of carbon therapy for a period of three weeks. It was a starting point of a success story that has led from fundamental research to a widespread medical application.

Sizes and shapes of nuclei with more than 100 protons were so far experimentally inaccessible. Laser spectroscopy is an established technique in measuring fundamental properties of exotic atoms and their nuclei. For the first time, this technique was now extended to precisely measure the optical excitation of atomic levels in the atomic shell of three isotopes of the heavy element nobelium, which contain 102 protons in their nuclei and do not occur naturally. This was reported by an…
