Theoretical descriptions of the first excited state of helium-4 are now consistent with experimental data. Despite the theorists’ successes, certain aspects of the experiment, such as the ...

Simulating the fundamental forces of nature on a computer is one of the grand challenges of modern physics, and a team at the ...

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 ...

Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts.

Tensor force is a crucial ingredient of the nucleon-nucleon (NN) interaction, and has an important impact on the structural and dynamical properties of the nuclear many-body system. Many efforts have ...
