spin-orbit matrix element

Explanation:
Detailed explanation-1: -All orbitals except the s-orbitals (l = 0), yield a doublet with the two possible states having different binding energies – this differece between the peaks is termed spin-orbit splitting (also known as j-j coupling).
Detailed explanation-2: -Spins interact with magnetic fields. The interaction with a static external magnetic field B0 is the Zeeman interaction, which is usually the largest spin interaction. At sufficiently large fields, where the high-field approximation holds, the Zeeman interaction determines the quantization direction of the spin.
