Last year, physicists at TU Darmstadt cast doubt on our current understanding of the interplay between electrons and atomic nuclei, and are now upping the ante by proposing a solution to this ...

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 ...

Last year, physicists cast doubt on our current understanding of the interplay between electrons and atomic nuclei, and are now upping the ante by proposing a solution to this so-called “hyperfine ...

Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the ...

The hyperfine structure of atomic spectra arises from interactions between the electromagnetic moments of the atomic nucleus and the surrounding electrons. These interactions, dominated by the ...

In a simplified picture, the electrons act as a magnifying glass, providing experimental access to the structure of the tiny atomic nucleus. Interactions between the electrons and the nucleus give ...
