Traditionally, a single spin-phonon coupling constant is used to characterize how effectively the lattice can affect the spin, but it is hardly enough to capture novel electromagnetic behaviors to the full extent. Here, we introduce a concept of spin-phonon dispersion to project the spin moment change along the phonon crystal momentum direction. (Fig.19) Effective "Z" becomes too big (= 3.5 ), if spin-orbit coupling is true. The central charge which 3p valence electron can feed should be close to Z = 1 also in sodium (= Na ). But when Z = 1, the calculated spin-orbit energy becomes too small, which cannot reach 0.0021 eV. When Z = 3.54, the fine structure formula gives this 0.0021 eV. Most experimental studies of spin-orbit coupling with ultracold atoms used two hyperfine ground states coupled by a two-photon Raman spin-flip process 10,11,12,23,24,25,26.So far direct evidence.

The spin-coupling term affects the energy levels of the electrons in an atom. Sometimes the energy levels that were thought to be degenerate are split into separate energy levels because of spin-orbit coupling, e.g., 2pzα and 2pzβ are not degenerate when spin-orbit coupling is taken into account.

In the case of the sodium doublet, the difference in energy for the 3p 3/2 and 3p 1/2 comes from a change of 1 unit in the spin orientation with the orbital part presumed to be the same. The change in energy is of the form. ΔE = μ B gB = 0.0021 eV. where μ B is the Bohr magneton and g is the electron spin g-factor with value very close to 2.
