the 1s state when the atom is immersed in a strong magnetic field B, assuming the electron Draw an energy level diagram (a) for the hydrogen electron in the 2p state and is spinless (10 pts). Next to this draw another diagram (b) when electron spin is included in the consideration (15 pts). Label the states clearly with the quantum numbers mi, m express the energy spacing AE in terms of the Bohr magneton B, and translate to the frequency splitting in the Zeeman pattern. Then draw dashed lines connecting the levels on both diagrams indicating how (b) is related to (a). 3B. (15 points) How can you distinguish between the Zeeman effect and the spin-orbit coupling (LS) effect from the pattern of the spectral lines? (5 pts) Draw an energy level diagram showing the effect of LS coupling on the 2p level structure of hydrogen. (10 pts) Label the levels in spectroscopic nl, notations.
