Hi,

In many quantum physics books I see questions such as "what is the spin-orbit interaction in this case?" Sorry if this seems like a dumb question, but what do they mean by this? Do they mean the ENERGY of the spin-orbit interaction or something else?

Also, could anyone give (or write a weblink for) the spin-orbit interaction? I searched a few books and online lecture notes from various universities, but I couldn't find anything conclusive.

These questions are basically asking for the strength or magnitude of the interaction, which indeed corresponds to the energy splitting of the levels. It is indeed sloppy language, and the questions could be better formulated.
