Fine Structure 35.1 Relativistic Hamiltonian
... There are relativistic and electromagnetic effects we have missed in our treatment of the pure Coulombic, classical approach. These are relatively easy to put back in perturbatively. Fine structure consists of two separate physical effects: one relativistic correction, one associated with spin-orbit ...
