... We consider the semi-classical problem of a spin-1/2 particle in a classical magnetic field. To each spin with spin angular momentum J is associated a magnetic moment µ = γS where γ is called the gyromagnetic ratio, a property of each spin-carrying particle (nucleus, electron, etc.). The energy of th ...

... In the following, we will use small letters for individual electrons and capital letters for multiple electrons. It follows directly from the comparison of equ.(5.09) with equ.(5.02) and equ.(5.04) that gL = 1 for orbital magnetism. This has been experimentally demonstrated with an accuracy of 10−4. ...
