Hi,

What direction does the electron's total magnetic dipole moment point relative to it's total angular momentum vector L+S? It seems to me that it would point oppositely to J=L+S since the spin magnetic dipole moment and the orbital magnetic dipole moment are both opposite to L and S, but this wikipedia entry

seems to indicate otherwise. What am I missing?

Read it again.

Is Gj negative? I'm not seeing it...sorry!
 
hi
Dear frindz i am confused about direction of dipole moment.why we take displacement vector from negative towards positive?

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
