... Since nuclei have spin angular momentum, just as electrons do, we need Skyrmions to spin when we want to describe nuclei as Skyrmions. Energies and allowed spin values of nuclei have so far almost exclusively been calculated by assuming that Skyrmions do not deform as they spin. We compute in the fi ...

So why are some isotopes stable and some unstable (radioactive)
... When an atom forms from sub-atomic particles, the atoms weigh less than the sum of the particles. This “lost” weight (mass defect) is converted to energy according to e=mc2. This energy must be replaced to each nucleon in order for an atom to break apart, so the lower this energy per nucleon, the mo ...
