Abstract

This interaction is weaker than the Coulomb interaction and is responsible for the fine-structure of atomic lines. How do we understand the spin-orbit interaction? • The electron has a spin s, as well as orbital angular momentum l. • For each angular momentum, there is an associated magnetic moment, and • Spin-orbit = interaction between and Let's start with the definition of magnetic moment…. l µ s µ Spin-orbit interaction (or " coupling ") H&W Chapter 12 l µ s µ
