Answer the fоllоwing shоrt questions: 1а) Identify аll the operаtors from J2, L2, S2, Lz, Sz that commute with Jz. (We are using standard notation e.g. J = L + S.) [5 points] 1b) Write the leading order perturbation Hamiltonian for the relativistic correction to the Hydrogen atom. Which, if any, degeneracies does the relativistic correction lift? [3+2 points] 1c) Explain why there is spin-orbit coupling. Name the quantum numbers on which the fine structure energy depends. [3+2 points] 1d) Explain why there is a hyperfine correction to the hydrogen atom. Which degeneracy does the hyperfine correction break? [3+2 points] 1e) Write |j = 5/2, mj= 3/2〉as a sum over |l = 2, ml〉|s = 1/2, ms〉states using Clebsch-Gordon coefficients. [5 points] 1f) An infinite square well defined as V = 0 for x ∈ [0,a] and V = ∞ otherwise, has the energy eigenstates ψn= √(2/a) * sin(nπx/a) for n = 1,2,.... In the center of the well we now put a delta-function bump:H′= αδ(x −a/2)where α
