Homework Help: Quantum Mechanics degeneracies in 3d potential

  1. Sep 25, 2014 #1
    1. The problem statement, all variables and given/known data
    What are the possible degeneracies and what is the symmetry of the position probability distribution in the case of a particle subject to a three-dimensional potential with cubic symmetry?

    2. Relevant equations

    3. The attempt at a solution
    With a three-dimensional potential, there are 6 ways to look at the wave function.

    Those are the degeneracies. The symmetry of the position probability distribution relies on the weighted average of the wave functions.
    Is this correct or is there a more direct way to answer this?

    You can directly find the degenerate energy levels for an infinite cubic well. It's a worthwhile exercise.

    The attempt at a solution is only valuable to understand that directions and their wavefunctions aren't unique for a cubically symmetrical potential.
