The splitting isotope shifts of C-12, C-13 and C-14 measured at COALA are in excellent agreement with high-precision QED calculations. Our paper has been published on 02.01.2026 in Physical Review A .

Our charge radii measurements from 104-134 Sn at ISOLDE with the COLLAPS and CRIS collaborations are published in Physical Review Letters . The measurements clarify the archlike trend in charge radii along the isotopic chain and reveal an odd-even staggering that is more pronounced near

TU Researchers publish study on triaxial structures

Laser Spectroscopy can be used to determine the relative size of different atomic nuclei of the same element by measuring tiny changes in their atomic spectra. We set up a novel apparatus for such experiments at Argonne National Laboratory and were able to reach outstanding sensitivity. These new developments allowed us to investigate the size of a series of radioactive ruthenium nuclei, which are known to be triaxial in shape: Similar to a coffee bean or an almond, all three axes have a different proportion.

Julian Palmes received a Giersch Excellence Award in recognition of his excellent progress with his doctoral project in 2024/25. Congratulations to our award winner!
