Homework Statement
Five electrons (with mass m) whose interaction can be neglected, are in the same 3-dim harmonic oscillatorpotential
[tex]V(x,y,z) = \frac k2 (x^2 + y^2 + z^2)[/tex]
What is the ground state energy?
Homework Equations
The Attempt at a Solution
I have the energy for the potential. It is:
[tex] E_{n_x,n_y,n_z} = (n_x+n_y+n_z + \frac 32)\frac{\hbar\omega}2[/tex]
My question is about the degeneracy.Since it's electrons, at most 2 of them can be in the same state, but can more than 2 electrons have the same energy?
Relating to this question: Should the ground state energy for this system be
[tex]E=2E_{111}+2E_{211}+E_{121}[/tex]
or are the two states (211) and (121) not allowed to have more than 2 electrons totally, ie
[tex]E=2E_{111}+2E_{211}+E_{221}[/tex]
