In addition, unlike atomic-electron term symbols, the lowest energy state is not L − S, but rather, l + s. All nuclear levels whose l value ( orbital angular momentum ) is greater than zero are thus split in the shell model to create states designated by l + s and l − s. Due to the nature of the shell model, which assumes an average potential rather than a central Coulombic potential, the nucleons that go into the l + s and l − s nuclear states are considered degenerate within each orbital ( e. g. The 2p3 / 2 contains four nucleons, all of the same energy.
