To see this, recall the definition of angular momentum: Kepler's second law states that the area swept out by the line connecting the satellite to the Earth's center over a given time Δt is a constant ...

and hence with the electron's spin angular momentum. Now a spin-orbit coupling that had previously been neglected is found to possibly be strong enough to give rise to an unconventional type of ...

Eight years later, the pair spin-orbit interaction (or spin-orbit coupling ... The effect depends on the product of spin and angular momentum (hence the coupling), taking their directions into ...
