What is the physical meaning "without spin-orbit interaction

[cytksu]

Hello.
I have studied about DWBA (distorted wave born approximation).
But, I do not know the physical meaning of "DWBA without spin-orbit interaction".
I think, I can not understand about meaning of spin-orbit.
How can I understand "without spin-orbit intertaction".
Thanks.

What is spin-orbit interaction in general, without involvement in scattering theory?

Amm... I don't know exactly... maybe electromagnetic interaction?

Well, then I'm afraid you're reading things beyond your current education level. I suggest you pick a good book on Quantum Mechanics (Shankar, Zettili, Brandsden and Joachain) and go through until you reach the "spin-orbit interaction" part.

Thank you for advice.
