An international research team lead by GSI/FAIR, Johannes Gutenberg University Mainz (JGU) and Helmholtz Institute Mainz (HIM) has succeeded in the production of a new seaborgium isotope. In the experiment conducted at the GSI/FAIR accelerator facilities, 22 nuclei of seaborgium-257 could be detected. The results were published in…

Researchers produce shortest-lived superheavy nucleus rutherfordium-252 and measure its subsequent decay

A team of researchers from GSI/FAIR, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has succeeded in exploring the limits of the so-called island of stability within the superheavy nuclides more precisely by measuring…

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? An international research team reports on experiments performed at the GSI/FAIR accelerator facility and at Johannes Gutenberg University Mainz to come closer to an answer. They gained insight into the structure of…

An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg-University Mainz and the Helmholtz Institute Mainz, succeeded in determining the chemical properties of the artificially produced superheavy elements moscovium and nihonium (elements 115 and 113). Moscovium thus becomes the heaviest element ever chemically studied.…

Progress in determining neutrino mass: Research group lead by Christoph Düllmann provides exotic samples for experiments

New physics in parity violation. From the Thomson limit to the energy frontier – Funding worth EUR 3.2 million

The consortium of Dr. Maarten Boonekamp (spokesperson, Institute of Research into the Fundamental Laws of the Universe, CEA, Paris-Saclay), Prof. Dr. Jens Erler (Institute for Nuclear Physics, JGU Mainz), and Prof. Dr. Frank Maas…

Helmholtz Linear ACcelerator-Kryomodul I has been completed and sent to GSI

On 01.03.2023 PhD student Nataniel Figueroa Leigh from the HIM section MAM defended his doctorate and was awarded the degree Summa Cum Laude.

Nataniel’s research is devoted to the development and implementation of new experimental techniques to search for dark matter and beyond-standard-model particles, using the techniques of atomic and…

In August 2022 the Wavy Dark Matter Summer took place in Mainz.

The 3-week event, which deals with the search for dark matter, was a great success.

Now there is a video about it.

Quantum technology on its way into society: In the joint project DiaQNOS, researchers from JGU and the Helmholtz Institute Mainz are developing quantum sensors to improve brain tumor surgery.

Removing a brain tumor presents surgeons with special challenges: They must remove the tumor, but without damaging healthy brain tissue. Among other…
