= = = (C:w).

As we have seen above, the spin-orbit coupling depends very strongly upon the nuclear charge and for very heavy atom it may outweigh the electrostatic interaction H es . In the perturbation approach, it is then necessary to first consider the influence from H s-o and then, as an additional perturbation, consider H es .

for jj Coupling Ensign Steven J. Gauerke, USN, and Mark L. Campbell United States Naval Academy, Annapolis, MD 21402-5026 The accurate description of atomic structure relies heav- ily on the coupling of angular momenta in the valence elec- trons of the atom. Such coupling is normally described in two limiting representations: LS or jj coupling.

LS and jj couplings are not spin-orbit coupling - they are techniques for giving quantum numbers to multi electron systems. Spin-orbit coupling is a relativistic effect from the dirac equation.
