1. The problem statement, all variables and given/known data Sketch the energy diagram for a system with l = 2 and s = 1/2: before spin-orbit splitting, after spin-orbit splitting, after additional application of external magnetic B (label all m values). 2. Relevant equations m values from -l to l (total 2l+1 values) j values from l-s to l+s mj values from -j to j (total 2j+1 values) 3. The attempt at a solution I drew a diagram but I'm not sure if it's right. and before the spin-orbit splitting I was confused, so I just drew the m values for l (not sure though).
