Degeneracy and orthogonality

  1. Nov 5, 2008 #1
    1. The problem statement, all variables and given/known data

    Are all electronis states orthonormal?
    I mean the degenerate states ie [n,l,m>states corresponding to same energy
    for example can one write

    2. Relevant equations

    3. The attempt at a solution

    for example can one write

    So you cannot write |2,0,0> as a superposition of the three l=1 states.

    Fine but how do you go about the proof???

    forget about in the wavemechanics
    just a general proof in bra-ket notation,showing that degenerate states are orthonormal.

    They are eigenstates of hermitian operators (namely, angular momentum) with different eigenvalues.
