It is seen that for heavier atoms, the nuclear charge causes the spin-orbit interactions to be strong enough the force between the individual
and .
- For large Z atoms, the electron-electron repulsion becomes weaker than the spin-orbit interaction of the individual electrons.
- In this case, the L-S coupling scheme can not explain the observed transitions from these atoms.
- The calculated energy levels from L-S coupling scheme fails to predict energy levels for these atoms.
- In the lecture, we will describe the j-j coupling scheme that describes the observed transitions from these heavy atoms.
