The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

Nuclear physics is the branch of science that examines the properties and behaviour of atomic nuclei, the densely packed assemblies of protons and neutrons held together by the strong interaction.

Researchers have combined theory and experiments to show that nuclear polarization does not limit studies of muonic atoms, clearing the way for new nuclear physics experiments. University of ...
