The neutron-rich unbound fluorine isotope 30F has been observed for the first time in an experiment at the SAMURAI spectrometer at the RIBF in RIKEN, Japan. The measured neutron separation energy shows no sharp decrease after N=20 providing the most direct confirmation that the N=20 shell gap is not restored in this region of the chart of nuclides close to 28O.

Laura Renth defended her dissertation entitled „Collinear Laser Spectroscopy of Magic Lead and Mid-Shell Palladium Isotopes“ successfully. Congratulations.

Oliver Papst (B02) defended his dissertation entitled “Exploration of Nuclear-Structure Effects on Averaged Decay Quantities in the Quasicontinuum” successfully. Congratulations.

Calculations of nuclear magnetic moments that take into account two-body currents are in better agreement with measured moments than ever before. The results published in Physical Review Letters range from relatively light nuclei such as oxygen to heavy elements such as bismuth.

Matthias Heinz (A04) won the 1st prize for his theory posters at the 2024 Conference “Direct Reactions with Exotic Beams” (DREB2024) with title “Improved ab initio description of neutron-rich calcium isotopes.”

Marco Knöll (A02,A04) hat seine Dissertation mit dem Thema „Ab-Initio Theory and Machine Learning for Hypernuclei” erfolgreich verteidigt. Herzlichen Glückwunsch.

The first CRC 1245 Mini-Workshop “Neutrino-matter interactions in the standard model and beyond” was hosted at the TU Darmstadt on June 19-21, 2024. The workshop featured main talks by Kirsty Duffy, Joanna Sobczyk, Javier Menèndez, Giovanni Benato, Baha Balantekin, and Zewei Xiong and an exciting program of talks by CRC members.

Matthias Heinz (A04) defended his dissertation entitled “Ab initio calculations of neutron-rich nuclei with many-body operators” successfully. Congratulations.

Benedikt Schallmo defended his dissertation entitled “Colour Superconductivity and the Equation of State of Dense Matter” successfully. Congratulations.
