Nuclear Term Schema (2002/06/20)  
Dan (02/06/20):
The nuclear term schema for an arbitrary nuclide is obtained by solving the Schrödinger equation for a modified 3dimensional harmonic oscillator potential. Taking into account the spin orbit interaction of angular momentum, Maria GoeppertMayer succeeded in analyzing the structure of the nuclear shells, interpreting the magic occupation numbers, and showing that protons and neutrons have slightly different higher terms. For any nucleon state, we denote by n ... the principal quantum number (oscillator shells with n = 1,2,...), l ... the orbital angular momentum (orbitals s,p,... with l = 0,...,n), s ... the spin quantum number (s = l/2 or +1/2), j ... the total angular momentum. Boldface state numbers denote closed neutron shells and are called nuclear magic numbers. The schema for protons is similar up to occupation number 82 but differs in higher regions.

The table below lists the few stable nuclides with doubly magic nucleon numbers.
