In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Thorium atomic ...

Atomic data determined by analysis of observed atomic spectra are essential for plasma diagnostics. For each low-ionisation open d- and f-subshell atomic species, around 10 3 fine structure energy ...

Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for suitable atomic nucleus states had been ongoing worldwide. In 2024, ...

Hyperfine structure arises from the coupling between electronic magnetic moments and nuclear spin and quadrupole moments, leading to minute energy‐level splittings superimposed on fine‐structure ...
