The nuclear force conserved isospin, which accounted for the similarities between protons and neutrons. Other forces, such as electromagnetism, broke isospin symmetry, which explained the nucleons ...

Thus, the excitation spectrum of atomic nuclei is immensely rich, as orbital, spin, and isospin degrees of freedom may be excited individually or in conjunction with one another.

The researchers realized a nuclear-spin dark state in a gate-defined silicon double quantum dot, demonstrating that such states can exist in real devices.

Advancing Nuclear Physics Research The team is now set to explore further how the initial properties of heavy ion influences the isospin transport processes in heavy ion collisions.

Now, nuclear physicists conducting experiments at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility have found new and unexpected cases of broken isospin symmetry.
