Spin-orbit interaction. In
quantum physics, the spin-orbit interaction (also called spin-orbit effect or
spin-orbit coupling) is any interaction of a particle's
spin with its
motion. The first and best known example of this is that spin-orbit interaction causes shifts in an
electron's atomic energy levels due to electromagnetic interaction between the
electron's
spin and the
nucleus's
magnetic field. This is detectable as a splitting of
spectral lines. A similar
effect, due to the relationship between
angular momentum and the strong nuclear force
?, occurs for
protons and
neutrons moving inside the
nucleus, leading to a shift in their energy levels in the nucleus shell model. In the field of
spintronics, spin-orbit effects for
electrons in semiconductors and other materials are explored and put to useful work. (wikipedia)
