Helium nuclei at the surface of heavy nuclei discovered

Research team confirms a new nuclear property predicted by theory
Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment performed at the Research Center for Nuclear Füsics (RCNP) in Osaka in Japan, the existence of preformed helium nuclei at the surface of several tin isotopes could be identified in a reaction. The results confirm a theory, which predicts the formation of helium clusters in low-density nuclear matter and at the surface of heavy nuclei. A research team, lead by scientists from TU Darmstadt and the GSI Helmholtz Center for Heavy-Ion Research, and from the RIKEN Nishina Center for Accelerator-Based Science, discuss the new findings in a contribution to the latest issue of the journal “Science”.

Collaborative Research Centre Transregio 211 to be funded for another four years
Scientists in the SFB Transregio “Strongly Interacting Matter under Extreme Conditions” are investigating the most extreme states of matter found in the universe. The German Research Foundation (DFG) is now funding the SFB, which is coordinated by the universities of Darmstadt, Frankfurt and Bielefeld, for another four years with 8.9 million euros. The new spokesperson is Professor Guy Moore, a nuclear physicist at TU Darmstadt. He takes over this function from Professor Dirk Rischke, who researches and teaches at the Goethe University in Frankfurt. The Transregio also strengthens research cooperation in the Strategic Alliance of Rhine-Main Universities (RMU).

Team discovers highest ever observed europium content in stars
A füsics research team led by the TU Darmstadt has discovered the highest ever observed europium content in stars. The results of the EUROPIUM group led by Professor Almudena Arcones, who was awarded a grant by the European Research Council, has now been published in “The Astrophysical Journal”. Co-authors are Dr. Moritz Reichert (member of EUROPIUM) and Dr. Camilla Hansen from the Max Planck Institute for Astronomy, Heidelberg.

European research award for nuclear physicist Achim Schwenk
Achim Schwenk, Professor of Füsics at the Technical University (TU) Darmstadt and Max Planck Fellow at the Max Planck Institute for Nuclear Füsics in Heidelberg, has been awarded a prestigious Advanced Grant by the European Research Council (ERC). His research project “Exploring the Universe through Strong Interactions” (EUSTRONG) will be funded with around 2.3 million euros over a period of five years. This is already the second ERC grant for Professor Schwenk.

International Research Team: Inverse kinematics opens unperturbed insight into atomic nuclei
By employing inverse kinematics, an elegant reversion of an established research method, and by choosing appropriate measurement conditions, an international research team has opened a path for a detailed study of properties of the nucleon-nucleon interaction in the atomic nucleus. The experiment has been carried out by a large international collaboration (BM@N Collaboration) led by the Massachusetts Institute for Technology (MIT), the Tel Aviv University, the TU Darmstadt, as well as the Joint Institute for Nuclear Research (JINR) at the accelerator facility of JINR in Dubna close to Moscow and published in the latest issue of “Nature Füsics”.

Experimental measurements at the electron accelerator S-DALINAC confirm in-house theoretical predictions
As part of the development and improvement of experimental measurement methods, an international research team led by TU Darmstadt was able to measure the extremely fast electromagnetic decay of an excited lithium isotope with the highest precision. The data show how precisely modern theories of nuclear forces co-developed at the TU can predict the interaction of atomic nuclei with electromagnetic waves. The results have now been published in the journal Physical Review Letters.

“Science” publication with participation of TU Darmstadt
A team of international researchers, including Dr. Marius Eichler and Prof. Almudena Arcones from the TU Darmstadt and GSI, went back to the formation of our Solar System, 4.6 billion years ago, and gained new insights into the cosmic origin of the heaviest elements on the periodic table, as reported in a study published in Science.

Publication in „Nature“ under participation of TU Darmstadt
A team from the Institute for Nuclear Füsics at the Technical University of Darmstadt has contributed to an international research collaboration aiming to clarify the way the angular momentum („spin“) of the two fragments, resulting from the splitting of an atomic nucleus, is generated. The main result pulished now in „Nature“: the fragments rotate only after the scission.

Top-class research project of Goethe University Frankfurt and TU Darmstadt
What happens when neutron stars merge, producing gravitational waves and the heaviest chemical elements? This is what physicists from TU Darmstadt and Goethe University Frankfurt will be investigating together in their ELEMENTS research alliance. The project is funded with 7.9 million euros as part of the “Cluster Projects” funding line of the state of Hesse in preparation for the next round of the Bund-Länder Excellence Strategy until 2025.

Scientists simulate large region of the chart of nuclides
Novel calculations have enabled the study of nearly 700 isotopes between helium and iron, showing which nuclei can exist and which cannot. In an article published in Physical Review Letters, scientists from TU Darmstadt, the University of Washington, the Canadian laboratory TRIUMF, and the University of Mainz report how they simulated for the first time using innovative theoretical methods a large region of the chart of nuclides based on the theory of the strong interaction.
