Consider the (eight) n = 2 states, 12 / m1 ms}. Find the energy of each state, under strong-field Zeeman splitting. Express each answer as the sum of three tenns: the Bohr energy, the fine-structure (proportional to a.2 ), and the Zeeman contribution (proportional to µ B Bext ). If you ignore fine structure altogether, how many distinct levels are there, and what are their degeneracies?
